I am a cs student at first class. Obviously we take an algorithm lesson. However, despite we have learned all things related to OOP , we didn't even learn switch case statement not even bubble sort algorithm or anything related to the algorithms. Because of that in my free time I learn this stuff individually. I know we will learn these things in the second class but it doesn't make sense to program anything without knowing them because you need to use them. You can use standard library but that doesn't mean you don't need to know how that works.
