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 (A_1 | A_2/A_3 | A_4) middot (B_1 | B_2/B_3 | B_4) = (A_1B_1 + A_2B_2 | A_1B_2 + A_2B_4/A_3B_1 + A_4B_3 | A_3B_2 + _4B_4) Show the steps that Strassen's algorithm takes to compute the product (1 0 2 1 4 1 1 0 0 1 3 0 5 0 2 1) middot (0 1 0 1 2 1 0 4 0 2 1 1 1 3 5 0) = (5 4 7 3 4 5 1 9 8 1 3 7 5 8 7 7) Exit the recursion when n = 2-i.e., compute the products of the 2 times 2 matrices using the brute force algorithm
