1. Show the correctness of Strassen's algorithm. That is, show that the seven multiplications of that algorithm combine to ensure that the computed product is A1 A2 B | B2 = A3 A4 B3 BA AB1+A2B3 | A1B2 + A2B4 A3B1A4B3 A3B2+ A4B4 2. Show the steps that Strassen's algorithm takes to compute the product 5 4 7 3 1 0 2 1 0 1 0 1 4 1 1 0 0 1 3 0 0 4 11 45 19 = 8 13 7 5 0 2 1 5 8 7 7 2 1 20 1 3 5 0 Exit the recursion when n = 2-i.e., compute the products of the 2 x 2 matrices using the brute force algorithm.
