I am noticing that recent CodeChef short contests(Cook-off and lunchtime) sometimes have some problems which have weak test cases leading to more AC solutions which are actually wrong a/c to the problem statements.
This becomes more irritating if you solved using some good tricks and Algo while others simply applying brute force and getting AC.
Many of us know some test cases where these wrong solutions will fail but we can’t do anything on CodeChef after the contest is over.
Suggestion- CodeChef should have a feature to hack other solutions after the contest like Codeforces has a 12-hour hacking phase in Div3 and Educational contest. This will decrease the wrong solutions getting AC and will help peoples to learn from their mistakes.
Please have a look @admin
