About discrete structure in CS class, a square matrix of dimension n is called a diagonal matrix if all cells except the left diagonal (cell positions (1, 1), (2, 2), (3, 3), …) contain 0. Suggest a quicker method (different from the standard method) to find the product of two diagonal matrices of size n.
