The divide and conquer approach for multiplying two large matrices of size 16x16 involves breaking down the problem into smaller subproblems. To multiply two matrices, A (of size 16x16) and B (of size 16x16), we divide each matrix into four submatrices. Each matrix is split into 4 submatrices, resulting in submatrices A1, A2, A3, A4 for matrix A and B1, B2, B3, B4 for matrix B. We then perform recursive multiplications of these smaller submatrices. The multiplication of matrices is done in a way that reduces the overall computational complexity by solving subproblems recursively. For matrix multiplication, we use the Strassen algorithm. This algorithm divides each matrix into 4 blocks (submatrices) and recursively computes the matrix product. Instead of performing the multiplication of submatrices directly, it computes 7 products of submatrices using additions and subtractions, which is __________ ___ __________ ______ _____ __________ ____ _____.
