Impossible One

https://www.codechef.com/BITM2021/problems/JAN20214

@pro_army Can you please look into the test-cases of the problem?, As I don’t think that this trivial problem can have zero solves unless there is something wrong with the problem statement or the test-cases or you wanted to make this problem impossible to solve no matter what :upside_down_face:.

No…actually it wasn’t meant to be that way. There was some issue in the test case generator created to generate test cases for this particular question.

The code used by our testing team coincidently passed the test cases which meant that the we weren’t able to know about the issue in generator.
Again, we are extremely sorry for the inconvenience caused by this question.
