Now it's just whether I can stick with it or not, it's very frustrating when the question marked easy and I have no idea how to solve it. haha. hoping one day I could solve problems marked hard easily.

@ionuttiplea4666 4 жыл бұрын

You probably want to learn data structures, they are very handy. After that you may want to focus just like Errichto said on solving problems. While doing so you will encounter the algorithms like Divide and Conquer, Backtracking, Quick sort and so on. You might also want to focus a little on the efficiency of each algorithm you do or you learn so that you might use the given data constraints in your favor, for example guessing what type of algorithm the optimal solution would be and see if you get an idea
