Question: Write pseudocode for a divide-and-conquer algorithm MATRIX-ADD-RECURSIVE that sums two matrices by partitioning each into four sub-matrices and then recursively summing corresponding pairs of sub-matrices.

Write pseudocode for a divide-and-conquer algorithm MATRIX-ADD-RECURSIVE that sums two matrices by partitioning each into four sub-matrices and then recursively summing corresponding pairs of sub-matrices. Assume that matrix partitioning uses (1)-time index calculations. Write a recurrence for the worst-case running time of MATRIX-ADD-RECURSIVE, and solve your recurrence. What happens if you use (n^2)-time copying to implement the partitioning instead of index calculations?
