How to figure out failing test cases?

Правка en5, от ldyllic, 2022-06-06 13:45:37

Hey, CodeForces!

I am seeking for your advice: how to improve my skills of figuring out test cases where my program fails? I have been facing quite a few WA on 100+, 300+ test cases and each of the times I wasn't able to get what was that edge case by myself. Hence, I am asking you guys for an advice :)

And in particular — what is the edge case here?

This is my submission: https://codeforces.net/contest/264/submission/159610034

Thank you all for your help!
