Multiplication time complexity
WebTime Complexity O (2N), N is number of matrices. Here we are trying to put parenthesis at every possible position. There are N matrices, therefore we can put parenthesis at N + 1 positions. Each position has two choices. Either a parenthesis can be put at that position or not. Therefore there are 2N + 1 total combinations.
