Wrong answer problem

sample test case output and my output both are the same but still, I am getting the wrong answer.
I am doing my code in python .can one plz help me.

Your code has to give correct answer for all hidden test cases. If the code gives the correct output for everyone of them, only then you’ll get an AC.

it have more then one sample case ??

i thought it have only one test case.i am taking the sample case as a custome input
and i am getting the same result but then also its showing wrong answer.actually i am new for this platform so i am getting it correctly.


there are some testcases which are hidden and designed to make sure that your code works for every possible edge case and under the given constraints

thank u so much
