CodeForces sheet

I solve DSA on LeetCode only. I have been doing a lot of DSA lately, mostly questions from Linked List, Arrays, and I make sure I see if I can do the potd or not.

Recently, I tried CodeForces,and I failed on the 1st test case. I was very demotivated, so I asked a friend how he does it. He told me I should solve the CP-31 sheet. Here is the link if you are also stuck at Codeforces. From today I will start doing it as well!!
