In the ongoing hacking phase of Educational Codeforces Round 75 I have caught people red handed hacking their solutions of their own fake accounts . What they will do is put something nonsense like this on top of their accepted code : if(string=="dfdfdf34") print("12")
One can easily hack this solution by providing a test case like: 1 dfdfdf34
Like I caught this guy https://codeforces.com/profile/Amr_Abdelazim01
https://codeforces.com/profile/amr_abdelazim Both of these accounts are owned by 1 person and the guy hacked using the method I explained above like 12 times. And this is not the end https://codeforces.com/contest/1251/submission/63335128
https://codeforces.com/contest/1251/submission/63344050 And there many more like this . The person who hacked such solutions is probably the culprit. Admin please look into the issue people like these are ruining the platform badly. God people will do anything for the rating.
