program is not running for this code.
no output is coming.
even errors are not coming if any.

Hi @yutikakhanna
Error is in line while((n–))>0) you do not have to compare n-- with 0 because when you do while(n–) then loop will automatically stop when n=0. So just change while((n–))>0) to while(n–) then all your test cases will pass.

Here is your corrected code :
