My issue

Problem Link: RNDPAIR Problem - CodeChef


In this problem I don’t know what’s the error in my code coz as I’m clicking “Run” the code runs perfectly and gives the expected ans.

And their is no logical error as I personally have verified with many test cases and I have verified through “ChatGPT” also , and it also say’s that my code is perfect as per the given statements and requirement.

I hope you will find a solution for my problem.

Problem is correct and your solution is wrong.
Bruh, “ChatGPT” doesn’t always provide the correct solution.

Then pls help me with the correct correct solution.
