The only reason i hate Interview Bit

#1

They fail to explain question properly, and we will waste days to understand whats wrong
and then some comment will tell us whats wrong. But by that time i have lost all interest in the problem.

#2

There is nothing wrong in the question and it’s pretty straight forwardly written. Feel free to ask your doubts.

Hello ktambili
What did you find unclear in the question?
I found everything to be clear(and was able to solve the problem), hence asking.
