** Rotate MxN Matrix May Do Oct 20, 2019 ・3 min read Rotate Matrix is a simple program that rotates a MxN grid by 90 degrees clockwise or counter-clockwise**. For example, the grid of [ [1, 2], [3, 4], [5, 6]] should return [ [2, 4, 6], [1, 3, 5]] when rotating counter-clockwise or [ [5, 3, 1], [6, 4, 2]] when rotating clockwise A rotation by 90 degrees can be accomplished by two reflections at a 45 degree angle so if you take the transpose of the matrix and then multiply it by the permutation matrix with all ones on the minor diagonal and all zeros everywhere else you will get a clockwise rotation by 90 degrees. For a 2x2 matrix this would look like: A B C Watch java videos Write a program to rotate a matrix (square matrix N x N) by 90 degrees (clockwise).

Here is the code you can use and test on a**matrix**of your choice - const rotate = matrix => reverse (transpose (matrix)); That's our solution! OK, not entirely. This is the final rotate I'll be using, but inside it, I'm employing two helper functions that have not yet been written: transpose and reverse. Note: This solution will rotate the matrix 90 degrees clockwise

These functions make transformations directly in the input matrix without utilizing any extra space which makes their space complexity as O(1) O ( 1). Thus, the final time complexity of this program is O(N 2) O ( N 2) and space complexity is O(1) O ( 1). In this way we have rotated a square matrix 90 degrees in anticlockwise direction without.
