Matrix Spiral Rotate

Given an m x n matrix, rotate it in a spiral manner by one layer. The outermost layer of the matrix should move inward one step in a clockwise direction, while the inner layers remain unchanged. Input format: - The first line contains two integers m and n (1 <= m, n <= 100), the number of rows and columns. - The next m lines each contain n integers separated by spaces. Output format: - The rotated matrix, printed row by row. Example: Input: 4 4 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Output: 5 1 2 3 9 6 7 4 13 10 11 8 14 15 12 16
