Answer / Rajani Sachan
In C, you can implement this as follows:n```cnint i, j, sum_upper = 0, sum_lower = 0;nfor (i = 0; i < M; i++) {n for (j = i + 1; j < N; j++) {n if (i < j) {n sum_upper += matrix[i][j];n } else if (i > j)n sum_lower += matrix[j][i];n }n}nprintf("Upper diagonal: %d
Lower diagonal: %d
", sum_upper, sum_lower);n```
