Hello I was checking successful hacking attempts in educational round #145, found that user [SCOR_PION](https://mirror.codeforces.com/profile/SCOR_PION) has **all** the submissions hacked by user [SAYANJIT7](https://mirror.codeforces.com/profile/SAYANJIT7). How is that possible? so I checked the submissions of [SCOR_PION](https://mirror.codeforces.com/profile/SCOR_PION). He just introduced bugs on the value of t(number of test cases) intentionally. And among the 14000 users [SAYANJIT7](https://mirror.codeforces.com/profile/SAYANJIT7) even managed to find him. How co-incident is that?↵
