I have a query related to the time complexity of the code.

Question: https://codeforces.net/problemset/problem/1265/B

My First Solution which was giving me timeout at 6th testcase: https://codeforces.net/contest/1265/submission/67753420

My Second Solution which got accepted: https://codeforces.net/contest/1265/submission/67753486

(Actually this is editorial code, I have copy pasted it).

Can please some one let me know why my first solution is giving me TLE and the second solution is getting accepted.

Merry Christmas.
