so everyone told me to practise...but the problem is that i set the problem set of codeforces to 1000-1200. Then i try to solve from the first problem. i was not able to solve it so i read the editorial or watched the solution from youtube. Then i move to another question from problemset. again i failed to solve it and then moved to another problem after watching the previous problem solutions. so overall i am not able to solve any problem by myself. i am new so need some guidance. do i have to continue doing this or am i doing something wrong.
