I was trying to submit the solution to the problem, but anyhow it is giving me wrong answer on the first test itself which is the same as in the problem.

The checker log says,

Can't find file C:\Contesters\Work\invoker-prod\work\codeforces2\05cb3343ceb9f6e3104ff51ff87bc7fb\check-8a86c82f5f45567b8e70d6a660570c0b\run\output.txt.

How to get around this?
