I am not able to implement queue of pairs it is giving wrong output everytime :slight_smile:

Hint to Approach the problem:

step:02: Now take the inputs and make the cases based on course and rollno.

Now first try to solve it on your own…
I provide you the Reference code also, you can dry run it…
