Yesterday, I was stress testing the solution of [problem E](https://codeforces.com/contest/1272/problem/E) of some random participants from recent Div 3, with my solution but i couldn't hack them. After a few hours, two solutions which i stress tested got hacked but miney stress testing couldn't catch where their solution was failing.<br>↵
So, how do people find such a test cases to hack other's solution? ↵
Any suggestions are appreciated. Thank you.
