In today's contest (Codeforces Round #628 (Div. 2)),I submitted Code of question [https://codeforces.net/contest/1325/problem/C](C — Ehab and Path-etic MEXs) in PyPy 3 I got pretests passed in 998ms Your text to link here....But after system testing My code got time limit exceeded on test 17,which I think was included in Pretests.I again submitted same code in same language as mentioned above and It passed in 982ms Your text to link here.... I'm very disappointed with this and want to hear your thoughts on that.
