Hello Codeforces!

During Educational Codeforces Round 130 (rated for Div 2) contest, I submitted my solution for Problem C 1697C - awoo's Favorite Problem in GNU G++17 7.3.0 and I got TLE on testcase 10 as verdict and after contest when I submitted the same solution in GNU G++17 9.2.0(64 bit, winlibs), what I saw, the code got ACCEPTED. This whole thing burnt my mind and that's why I am writing this blog.

Here's a proof for the same I mentioned.
For solution 160374839, got TLE as verdict.
For this solution 160450643, got ACCEPTED.

MikeMirzayanov please looks into it and explain it properly and also if possible accept my solution.

Guys please upvote if u are agree with this.
