I FUCKING MADE IT GUYS! I JUST PASSED THE HARDEST COURSE AT UNIVERSITY WHICH IS ABOUT DATA STRUCTURES AND ALGORITHMS! I DRAGGED THIS WITH ME A WHOLE YEAR AND I JUST GOT THE NOTIFICATION THAT I MADE IT. I'M SO FUCKING HAPPY GUYS I CANT BELIEVE IT!!!!!!

This guy is the best coworker ever. He analyzes my algorithms, advises me when to eat or take breaks, and reminds me not to take life too seriously. He's pretty helpful with debugging too.

Embrace the notch!

How great algorithms are made!

"Hey, can you help me with our Algorithms & Data Structures task? I tried to tranlate my problem with Google translator but I can not select the option to translate into Java."

I was speechless when a girl actually asked me that

This is brilliant 😂😂

Me: "I'm a programmer"

Others: talks about linux
Others: search algorithms!
Others: service infrastructure
Others: memory optimization
Others: encryption

Me: "I'm a front end web developer"

Others: complex services
Others: strong user form validation
Others: lazy loading
Others: SEO

Me: "fucking, I make shit look pretty alright"

A substring problem? Here, have 3 nested for loops 😏😏

Today I discovered MIT OpenCourseWare.

I hate university, and I usually doze off during lectures, but my god, I've been listening to "Introduction to Algorithms" for about 6 hours now, and I'm hanging on to every word.

solving algorithms and ds problems :-

In C++ - I hate pointers.
In Java - I miss pointers

Yay practical algorithms!

Gets me everytime :3

1. You will write ugly code. Code that is in dire need of refactoring almost immediately.

2. You will write brilliant code. Functions and algorithms that will impress all that use them.

3. 1 & 2 are not mutually exclusive. Good software can be written poorly, beautifully written code can be useless. At the end of the day, just get the job done.

True story!!

Familiar with this Book?
My Teacher said it's the Bible of Algorithms for Beginners.

If you like Google algorithms better, you can always just precede your duckduckgo search with !Google

No caption! Its itself explanatory 😂

DevRant uses *coding* and *algorithms* to humiliate ranters

when ur parents try to understand what u do.

Was recently phone interviewed by a recruiter that asked "So do you know data structures and algorithms?" I replied "That's like asking someone if they know Mathematics - can you be a bit more specific?"

Protip: appending ", dammit" to your Google searches tells their NLP algorithms that you need more relevant results

"They used coding AND algorithms"
Wow I didn't know that you can use those together!

Agree.

I want to thank every Indian computer scientist on Youtube. Because of these guys I passed my Algorithms and Data Structures Exam.

Me: Browsing the security of a website.

Tell the website developer that they are using the SHA-1 hashing algorithm for encrypting the credentials of it's registered users.

Them: Yeah, so what?

Me: You shouldn't be using an algorithm which was exploited years ago in the age of 2016.

Them: Don't worry, nothing will happen.

Me: *facepalm*

Goodbye web development; welcome back algorithms and scripting... How I missed you so much in these agonizing days we've been apart. But fear not, I shall never return to web development...

Well, I still have important websites to finish, but I won't let web development become my niche.

when you screw up at a coding interview because you couldn't remember an algorithm you havent used in 7 years.

Wonder if I'll ever feel like a real programmer in web dev surrounded with C++ gurus that eat, sleep, and breathe memory allocation and optimization algorithms. I'm just over here like... You can go to this link and a pretty red box moves around on the screen

I run very fast; Almost at O(1)

I hate bullshit metrics, they are everywhere.

- 90% unlimited downloads (not unlimited then is it, dickface)
- you are 53% more likely to be noticed with a pro account (yeah, because you fucked with the algorithms)

Algorithms strike again :D

By the way I really much agree on both rants. People asking questions that they not even once typed into Google. Disturbing my workflow every 5 minutes...

Some top-notch learning algorithms you have there Google 👌

The index to Sedgewick's Algorithms book says:

This is triggering me sooo much!!!

What does sorting and sex have in common? In both cases we hope for a great Big O.

Can anyone recommend good books for coding algorithm​s?

Any tips and tricks would also be helpful. Thanks.

Today is my fourth try to pass advanced algorithms. Wish me luck.

Today during my Algorithms lab, the guy sitting to my left began digging his nose like he had buried treasure there. 🤢
Oh how I wanted to smash his face on his keyboard. 😭

After solving a lot of problems in codeforces and participating in ACM to make my code the most optimised..
* In my first real job. *

Boss: tell me about the new release.
Me: updated the search algorithms boss.
Boss: cool. Release!
Me: 😎

Hey! How do I do machine learning?

Well first you start off with a metric shit ton of data.
And then you .fit() your data
from there you can .predict() your data

Trust me, the algorithms are already there. All you need to do is get the data.

While learning algorithms. That shit was amazing!

I got ranted,by our teacher in algorithms lab, because I was compiling the code using terminal and was not using torboC (there wasn't any IDE installed on the system) 😃

Sometimes I feel MS Excel is more intelligent at predicting my next moves whenever I open a new sheet than Google's AI and ML algorithms who have been tracking me for years now.

Had to hand in as assigment for my algorithms & data structure course and really put alot of work into it, commented code, easy to understand and all.
"Why are you showing me copied code from the internet?" was the professors answer...
I did not copy any code and some algorithms often look the same...

Why do snails and slugs hate security algorithms?

Cause they might contain salt.

When you implement an algorithm on your first try:

Diving into genetic algorithms right now (its 4 am), am i just a rare specimen or is this not hard at all?

After watching Mr Robot, I installed Kali and learnt to hack WiFi passwords via brute force. Was utterly disappointed that, most crackers just use prebuilt tools instead of developing their own algorithms and programs.

If coding was a thing 100+ years ago, we'd have quotes by great men like "You won't have space for new ideas unless you shit out the old ones in the toilet." which would be an alternative for "the toilet is the best place to think of algorithms and fixes."

This is documentation at a noob-program level. We had this one teacher, who shall remain unnamed, who used single letter variable names everywhere, who couldn't understand his own programs when they were shown to him.

Not only coding, but studying Computer Science has changed a lot in my life. For example, learning about CPU scheduling algorithms made me manage time for my personal tasks a lot better. Earlier I used to waste a lot of time by doing tasks in out of sync order. Also coding made me realize how dumb most people are!

Got introduced to RLE on a rant the other day and holy shit doing more research into it and it's algorithms... How the fuck have I not known of this?!?!?!

Why do I keep having dreams of code and algorithms? Let me sleep!

That feeling when recursion finally "clicks", and you begin instantly identifying candidates in your code for recursive solutions.

What's the best way for someone who is terrible at maths to get better at algorithms. I'm pretty good at programming but when it comes to write an algorithm, it scares me because of my poor math.

Is there another way or do you think going back and starting maths from scratch will help?

Learning neural network algorithms and feeling very accomplished........

.......then checks out OpenCV and flips desk.

I was absolutely angry, my ego had been wounded. I had built the entire product from scratch, while my bosses just clinged onto one feature that i had not done.

It wasn't even going to be used i knew that and hence was slack. It also required a lot of algo writing.

Post the discussion i decided I'm gonna take out my hurt ego's anger on this algo. I drank whole night and coded. Damn fucking one of the most complex logics i had ever written. It was done and tested while the sun rose. And i slept, next day was a Sunday. I couldn't get hungover.

I was wrong, the logic was used and is one of the core logics of the product. Something that we boast of. 😁

How many of these algorithms do you know

Heuristic algorithms.

I just wrote unit tests for like the first time in my life (didn't find it useful in university, someone else handing in the project always did that). It cut my coding time by a factor of 3! You should try this one if haven't already, it really saved me a lot of headache right now.

For starters this is my first post, found devrant the other day you're all hilarious.

I hate math, I hate proofs. I'm in a class "Analysis of Algorithms" and I have understood and do understand the importance of optimizing algorithms and data structures and I understand the algorithms and data structures themselves. That being said, I'm fucking sick of math and proofs and all this bullshit that is probably pretty important but ugggghh, I guess I just have to push through, but writing this out helped.

Me trying to impress my girlfriend with the light painting.

Motivated me to develop my own algorithm for the effect.

Yesterday, while I was studying for an algorithm exam, I realized I used induction on trees in a wrong way for six months.

So just finished my last algorithms and data structures class frequency, feeling pretty confident about the grade, today it'll be all weed, pizza and sex. Life is good :')

my vision about life changed as I started learning about algorithms and programming, which I consider as an advantage, tho I can't help but wonder if people in different fields feel the same.
it also feels like I over-think since then, a constant need to analyze things which is overwhelming sometimes.

So in my last post I was angry that I didnt know many algorithms or how to make one, so you guys inspired me to learn about them and I found a course I'm gonna take about algorithms and such. I'm incorporating it into my learning schedule so let's hope this leads to me not being stupid.

Due to the constant change in accuracy of my keyboards' predictive algorithms, I now find myself switching between SwiftKey and GBoard... 😢😔

Anyone else feel the same?

Don't get the logic where good understanding of algorithms is only needed for backend developers.

is it normal that i go to the 2nd best cs college in my whole country, also ranked in top 200 colleges globally in the world, and they don't teach us anything about algorithms?

My 2018 goals:
1. Graduate from the Deep Learning Nanodegree.
2. Get better at Python.
3. Learn C++.
4. Learn more about Machine Learning and AI.

That moment, when you meet someone who haven't written even a simple if-else statement in their life and want to work on Deep Learning algorithms using TensorFlow. World is filled with so many ML crazy peoe.

Fellow Deviants, I need your help in understanding the importance of C++

Okay, I need to clarify a few things:

I am not a beginner or a newbie who has just entered this community...

I have been using C++ for some time and in fact, it was the language which introduced me to the world of programming... Before, I switched to Java, since I found it much better for application development...

I already know about the obvious arguments given in favour of C/C++ like how it is a much more faster and memory efficient than other languages...

But, at the same time, C/C++ exposes us and doesn't protect us from ourselves.. I hope that you understand what I mean to say..

And, I guess that it is a fair tradeoff for the kind of power and control that these languages (C/C++) provide us..

And, I also agree with the fact that it is an language that ideally suits our need, if we wish to deal with compilers, graphics, OS, etc, in the future...

But, what I really want to ask here is:

In this age and times, when hardware has advanced so much, where technically, memory efficiency or execution speeds no longer is the topmost priority... These were the reasons for which C/C++ was initially created...

In today's time, human concept of time matters more and hence, syntactical less complicated languages like Java or Python are much more preferred, especially for domains like application development or data sciences...

So, is continuing with C++, an endeavour worth sticking with in the future or is it not required...

I am talking about this issue since I am in a dilemma about the use of C++ in the future...

I would be grateful if we could talk about keeping AI, Machine Learning or Algorithms Optimisation in mind... Since, these are the fields in which I am interested in...

I know that my question could have been posted in a better way.. But, considering the chaos that is present in my mind, regarding this question doesn't allow me to do so...

Any kind of suggestion or thoughts would be welcome and much appreciated...

P.S: I currently use C++ only for competitive programming or challenges...

Holy shit man...

I know its supposed to be hard but I cant ignore how much I want to give up right now.

I've been learning JS for months now, doing daily algorithm challenges, going strong on my freecodecamp dev map and still, I feel like I might no be cut out for this.

It's been more than a week now trying to implement a minimax algorithm into my tic tac toe game. I can't, for the life of me its just getting more frustrating by the day and its driving me crazy! How the fuck am I supposed to ever get a junior webdev job if I can't do something as simple as this!, And I keep reading and reading the theory but I cant implement it into my code! It just makes me want to quit (again)!

I really need to work on my attitude...

Been watching some videos on Algorithms and my mind bleeds. Do people who know this stuff really calculate complexities for each method they write?

To the one who did a degree:
How mush do you use the algorithms you've learnt in the college/University?

Writing "Algorithms and Data-structures" exam in an hour.. Only coding C++ on paper .__.

Things that make me mad in school: when "ap computer science" is a class that literally just teaches you Java syntax and nothing about any theory and algorithms. Like c'mon

I just officially graduated from a web dev program and it feels...

Very underwhelming.

Learned ES6, React, Webpack, service workers, offline databases, accessibility, (...bla bla bla)

And my knowledge with data structures and algorithms isn't even that great yet.

I look at the stuff I still don't know and wonder if I'll ever be comfortable with my level of expertise.

Does anyone here know a good book about algorithms? I'm looking something a bit more advanced

Design patterns are algorithms without loops 🤓

I don't know why they made so many algorithms, data structures and big O questions during interview, when all they wanted me to do was to maintain some legacy, tight coupled, spaghetti code with no architecture, documentation, tests nor any kind of engineering behind :/

studyng algorithms and data structures :(

What do you think about this level Inheritance 😃

I always feel inspired by programming when I create some algorithms or programs which I can use when I need to.

Small utilities and command line programs r what I make at times... and I also enjoy trying to implement them awesome algorithms 😍

However, most inspiration I get is from looking at C code though ( especially the Linux kernel... that code is SO clean 😍😍 )

I know this sounds odd, but I really find algorithms things of delightful beauty.

A creative solution to some very deceptively complex problems.

Sure, some implementations aren't the best, but seeing them after just makes me appreciate the time and effort that must have gone into designing things like Merge Sort, Binary Search, Greedy Algorithms, BST, and Dijkstra's Algorithm.

So! If your code is unoptimal, looks terrible, or is a sheer abomination, take a moment to appreciate the little piece of art you've made before you go and make it better.

Just implemented A* and Dijkstra to get into pathfinding with graphs. Really hyped about this! TIL that Dijkstra is perfect to find the quickest subway route in my city 😏

I haven't touched algorithms for many months but needed to create a matching algorithm today.

It has to match using variations of the original key and output the keys that can't be matched.

The feeling in my head felt like I was turning rusty gears n sort of just stumbling through...

I used an N^2 approach but afterwards it just felt wrong... And it took me like an hour of hacking to do it....

Actually I just realized it's an N approach! because all possible matches would be hit by iterating from one of the lists of possible names!

I suddenly feel so proud of my subsconcious...

But still something doesn't feel right...

Fucking recursive algorithms. Does anyone actually use them when programming in real life?

Finished a program for my friend’s bachelor thesis in just 2+ hours (and some),

I hate when theres simple problems I cant solve. Legit pisses me off. I cant even program a simple number sorting algorithm. 🤬

Worst sorting algorithm in your opinion?

I don't get it. Why do front end devs need to learn algorithms to get their interview done?

When you show the client the comprehensive administration system they ordered but their young female HR leader is "more into pictures than tables".

I have a problem to solve but I just can't come up with any working algorithm or idea to solve it. I feel really fucking stupid right now

What do you guys think about people who call themselves programmers after learning few technologies from Onlinecourse’s . I don’t want to call someone programmer who doesn’t know very important and useful concepts called data structures and algorithms.

3. Participate again in one hackathon and kick their ass after winning it
4. Get one awesome internship
5. Master algorithms and DS

Generator functions should be treated like sorting algorithms: Not worth your time if all you have is 4 or less async instructions.
Callback hell is actually kind of nice and warm when you're a just a few levels down. If you're really confused by your obfuscated code, you suck at node.

CS majors be like:

"She got a big theta, so I call her big Oh."

I already forgot what are the different sorting algorithms I learned last week. I already forgot sin, cos, tan, log, and some Math concepts in school. How not to forget these things easily? I could recall them once I see a sample and a brief explanation.

Anyone wana recommend me books for algorithms and data structures?

I hate C++

when you forget simple algorithms while coding :(

For now on I am just going to say I am a Psychologist... for computers. And my algorithms are what shape the behavior (:

I will have to present some algorithms at our school festival next week.
Any idea for a good real world example to demonstrate how breadth first search works?

I feel i am the only one in my class at uni who actually likes algorithms :D

Got rejected in an interview today, because I lack knowledge in Data Structures and Algorithms. 😔😞

I guess I'll have to bursh up my Algo skills again.

A music server where people can login and add their own music to channels, with request lists and priority lists algorithms. Welp atleast the streaming part is done

Definition of Algorithms...........

What are some of the most interesting algorithmic problems you have faced?

In an algorithm class, professor introduced us to some simple search algorithms (bubble sort, selection sort, insertion sort, shell sort). He did a quite decent job and most of the students were able to grasp the code and understand the differences in those algorithms. But then he spoiled his whole lecture with one additional slide. There he proposed an optimization: Instead of using a temporary swap variable, we just could use the first array element (or the zeroth element, respectively: the one ad index 0) for doing all the swapping. We just had to document that, so that the caller would "leave the first position of the array empty", resulting in "cleaner code". And he did that in the same class where he used Big-O notation to argue about runtime complexity. But having the caller to resize the array and to shift all the elements by one position did not matter to him at all, because it was "not part of the actual algorithm".

Me(the first day fo spring semester): Data Structures and Algorithms shouldn't be too hard of a class! This will be interesting!

Me(a couple days into class): I don't understand anything she's saying and the programming problems are in some pretty rough English...why me?!?

Anyone else like... REALLY bad at algorithms and logic stuff?

I just hate them so much.

Tell me to build something and gg done. But all these tests for jobs freak me out.

Like. It probably ends up being something simple and when it's explained I know what to do but at first I just instantly shut down and can't think.

!important in CSS and not commenting complex algorithms in c#

What do you guys think about competitive programming, how does it impacts your programming in the long run?
I feel depressed when I take more than enough time to complete a competitive programming challenge marked as "Easy". 😥

I just realized my male brain is horrible at multithreading. ++ to all womens and their amazing algorithms and capabilities 😘

A newbie trying to understand Algorithms....suicide. No jokes here.

Anyone else think the class algorithms in college was difficult?

I want to adopt this habit of coding one fundamental concept/tool/.. every day before/after work. I already started doing it and I've been coding sort algorithms. every morning since last week, in Java.
What do you guys think should go on the list of things to practice regularly ?

i wish i had no university classes (or at least, only programming classes) so that i could learn more about different technologies and had more time to code :(

I am afraid of programming

How do you think recursively? Any tips?

I know how to code. I am good at coding, algorithms, datastructures. I have also been using linux since 4 years.

But still I am not a programmer. I work on excel in office.

When developing for Android, when testing algorithms or code that isn't platform specific, I always do it in a separate Java project open in eclipse instead of in the actual project. Who else does this/something similar?

Is it true tho ?

My CS department's professor for our algorithms class (learning stuff like big O, shortest path, etc.) was tenured and hated teaching. He preferred working on his research but was required to teach as part of his tenure. Not only did he hate teaching, he was also bad at it.

This man would stand at the front of the room, mumble into the chalkboard (we still had chalkboards in 2010 for some reason), and work through algorithm proofs. You could not hear or understand him past the 1st row. Occasionally, he'd make a mistake on the board, realise it halfway through the proof, go back, change it, and continue on with absolutely no explanation.

The class as a whole hated him because we literally were unable to learn under him. We ended up going to the department head. The department head thought he was going to be dealing with 1-2 students complaining about a professor for no reason. Instead, he got 12 students (half the class) who all said they couldn't learn under this professor and detailed the problems.

The department acted on this by getting the prof a TA to help explain what was going on to the class and hired a lesson plan writer for him. Remember, this is a professor with tenure and who has taught this class for about 20 years.

I had to drop the class to save my GPA before the changes took effect because my grade was too far gone, but the students that stayed noted a marked improvement.

I got this prof again the next semester and all of the changes they made the previous semester were dropped because it was too expensive for the department to keep up with. I manage to power through with help from a kind TA and walked out with my C.

When I graduated, we had the opportunity to discuss anything we wanted about the programme with the department head in an exit interview. Few students show up to these because they're optional, but I made sure to do so.

I told tales of the great professors I had throughout my degree and then moved onto this guy.

I told them they need to either have him stop teaching or do something about his tenure because he was actively preventing students from learning a critical part of their degree programme.

The response I got was as follows.

"So we get complaints every semester and during these exit interviews about this professor. We know he's terrible, but his tenure prevents us from doing much. We keep encouraging him to retire, but at 70 he still refuses to do so. He actually had a heart attack about a month ago and while he's recovering fine, we're hoping that this pushes him to finally retire."

Seriously, I get that tenure is helpful in some scenarios, but when you have to hope that a professor either dies or retires because you can't do anything about how bad he is, tenure isn't working right.

One of the best algorithms I have designed ever
