Rotate Matrix 90 Degree Clockwise ID:2668

A MxN matrix is passed as the input. The program must rotate the matrix by 90 degrees in clock wise direction and print the rotated matrix as the output.

Input Format:
First line will contain the value of M.
Second line will contain the value of N.
Next M lines will contain the N values with each value separated by one or more space.

Output Format:
N lines will contain the M values with each value separated by one or more space.

Boundary Conditions:
2 <= M <= 15
2 <= N <= 15

Example Input/Output 1:
Input:
2
