I have been flagged in starters 158 but this is not true

Dear Codechef Support Team,
Today, I got the notification that my account has been flagged for cheating in starters158. But this was not due to any cheating on my part, but someone else may arrive at the same logic for solving the problem. You can review all three submitted codes, given the nature and difficulty level of the question.
Kindly go through my code again and make a proper decision.
Thank you.

@emperor100 please look into my matter and solve this before the next contest (starters 159)
