Hi,

Have been trying this problem for 4 days now. My solution is the same as that provided in the editorial but I just keep getting WA :/

I have checked my solution with thousands of small test cases and a python brute force solution (with n upto 100) and it has matched all of them.

Here is my C++ code

This is my brute force python solution

And this is the test case generator

Kindly help me. Thank you! :)
