During Educational Codeforces Round 116 (Rated for Div. 2), I try to submit my solution for question c in c++20 when there were around 850 submissions. But due to some reason, I kept getting the wrong answers. When I submitted it in c++17, it got accepted. You can see my submissions. Kindly look into this matter, I want to point out the bug rather than focusing on anything else. MikeMirzayanov
