The program must accept two square matrices which are of size N*N. Then the values in the matrices must be printed spirally in clock wise direction in a single line. The values in a specific row or column of the first matrix must follow the values in the same row or column of the second matrix.
Boundary Condition(s):
1 <= N <= 30
1 <= Integer value in the matrix <= 1000
Input Format:
The first line contains N.
Next 2N lines contain N values each (First N lines contain the values in the first matrix and the next N lines contain the values in the second matrix).
Output Format:
The first line contains 2*N*N values in the two matrices printed spirally.
