PROBLEM:
You have to print clockwise rotations of a given 2-D array at given times, provided there is one clockwise rotation of the array per unit time.
EXPLANATION:
Whatever be the times at which the array is asked to be displayed, it can have only four states which can be found by taking T modulo 4, where T is the time at which we need to print the array. With some observation, the array can be printed easily by altering the looping variables.
