What changes to do in code ..please correct

#1
#2

@neelrai906 First thing is take the size of pair array till something like 1005. because it is the constraint.

Also make a extra counter for if , case so that you can count the number of compressions.
At last print the pair from 0 to till that extra counter you made.

Do these changes your code will pass.
Feel free to ask, if you are able to solve it then please mark it as resolved.
