Write a complete C program which prints the index of a submatrix in a given matrix. Read two integers: n, m from the user, and read two matrices A, B with the sizes nxn and mxm (assume n>m). Assuming the second matrix B appears in the first matrix A exactly once. Find the position (row and column values) of the upper-left corner of the second matrix B in the first matrix A. For example: Input Result 3 2 1, 0 1 2 3 4 5 6 6 76 4 5 67 1, 1 4 2 1 2 3 6 4 5 6 7 67 68 1 2 3 4 5 6 76 Answer: (penalty regime: 0 %)
