A University named "XYZ" sends the question papers for different subjects to different colleges in a zipped file along with a secret key to access them.

If K is positive, displace to the right and if K is negative, displace to the left. The lower limit and upper limit of the character's ASCII value generated after K displacement is 65 and 126 .

The squads perform these steps to find out the password r
