Hello Code Forces, Hope you are Doing Good While solving some of the problems from Problem set I some times get unable to figure out what could be the test cases where the my code give wrong answer Could you Recommend How analyze the test cases for the given problem and Secondly when I participate in the contests while attempting the problems I made many wrong submissions due to which I get lesser score and ranks become horribly bad So could suggest something so that I made very less or no wrong submission while attempting the contest Thanks in Advance!!! Have a Great Day Ahead And Sorry if this question/blog was silly

Plz It's the request to resolve the issue as soon as possible So that I can give more time to codeforces rather than other sites Thanks to the codeforces team to resolve the issue in future
