Mass Cheating in every Leetcode Contest (More shorts on this New Channel) - kzbin.infohH473URZWnk?si=VHvc-zg59h7kbR-u

[@unknown07711]

The main reason of cheating is that students are more focusing on rating rather than taking it as practice ...

[@emon4912]

I also thought of prefixSum but was confused of what to kept as prefixSum. Your step by step approach was so helpful.

[@kingxkaushal]

[@anshthakur4677]

Can also be solved using lower_bound✌️

[@yashkalia2311]

i solved it too

[@bishwashkumarsah171]

[@goyaldeekshant]

nice one

[@rev_krakken70]

I solved the second question using binary search. That concept seemed easier for me to understand rather than the prefix sum one

[@AdityaGupta-kv5ip]

I solved it using segment trees and after solving when I saw the editorial I saw that there was not even any one solution using segment trees lol and not even the problem tags mention segment trees😂
