Basically I want to know how many loops we can iterate in 1 sec because according to me this number is approx 10^6 but in ques A of given link: https://mirror.codeforces.com/contest/1341/problem/A, I submitted a solution with brute force by thinking that it takes a maximum of 10^6 loops so I will not tle in system cases but that doesn't happen my solution got tle later and I relook into that solution and also not getting the reason why this solution get tle as it takes a maximum of 10^6 loops. Solution link: https://mirror.codeforces.com/contest/1341/submission/77777541. So please anyone explain to me the reason for this. Thank you
