I tried submitting a solution to https://codeforces.me/contest/1820/problem/C, and for the first test case, my ide gave the correct solution. However, when I submitted the code to codeforces, it says that my output for the last test case was "YES", despite how the ide says that the output was "NO". Why is this happening?

Thank you!
