Non-overlapping Square Submatrices

The program must accept an integer matrix of size RxC as the input. The program must print all possible non-overlapping square submatrices in the given matrix as the output. The non-overlapping square submatrices must be printed in increasing order of size.

Boundary Condition(s):
2 <= R, C <= 30

Input Format:
The first line contains R and C separated by a space.
The next R lines, each contains C integers separated by a space.

Output Format:
The lines containing the non-overlapping square submatrices.
