I firmly deny the allegation that I copied someone else's code or provided any form of assistance to other contestants during the coding contest.
In my code, I have used variables like 's' representing string, 'x' and 'y' representing x and y coordinates, and 'f' for flag which is very common, I am confident that the code I have submitted is entirely my own and that I have followed all the rules and guidelines of the contest.
This is a pure coincidence and I hope that this issue will be resolved quickly and fairly.
