I don't know if people solve coding problem here too .

Please i need an algorithm to remove redundant data inside an array of string

Well, first of all you need to write an algorithm to figure out what data at which index is redundant.

Google/Bing/Yahoo/Yandex/DDG has the answer.

That's an interview question. We're more likely to help when you have a problem with some meat on it.

Compression? More efficient encoding?

In C#

stringEnumerable.Distinct();

Function remove_duplicates(list)
arr = Split(list,",")
Set dict = CreateObject("Scripting.Dictionary")
For i = 0 To UBound(arr)
If dict.Exists(arr(i)) = False Then
dict.Add arr(i),""
End If
Next
For Each key In dict.Keys
tmp = tmp & key & ","
Next
remove_duplicates = Left(tmp,Len(tmp)-1)
End Function

Assuming it's all redundant:

arr = null;

Assuming it's not, more detail required. And an attempt at a solution.

@AlmondSauce it's as if you didn't get the thing

here is an example

If you have a table with redundant item like this
T = ['cc','aa','ab','aa','cc'];

The output need to be like this
O = ['cc','aa','ab']

yeah

@12bitfloat

JavaScript has an inbuilt function for that.

@Afrographics I just think it's funny how you say you are an experienced dev when you have problems writing your own deduplication function. A performant one may be harder but a simple one is literally just a hashset lookup

@12bitfloat it's just a waste of time for me to re-invent the wheel.

in C/C++. I didn't find an in-built function for that.

So that is i wanted to code it. Myself. And i have already found the solution

Alone😒

@molaram ok how much do you charge for an interview question?

@Afrographics 5 bucks

@12bitfloat ok but i solved mine

Next time

@Afrographics Just let me know lol

@molaram 🤣🤣🤣🤣

🏃🏃🏃

Let's just drop that then
