Spiral Matrix

The problem Given an m x n matrix, return all elements of the matrix in spiral order. Examples Input: matrix = [[1,2,3],[4,5,6],[7,8,9]] Output: [1,2,3,6,9,8,7,4,5] Input: matrix = [[1,2,3,4],[5,6,7,8],[9,10,11,12]] Output: [1,2,3,4,8,12,11,10,9,5,6,7] Constraints m == matrix.length n == matrix[i].length 1 <= m, n <= 10 -100 <= matrix[i][j] <= 100 Explanation Let’s look at the example with matrix = [[1,2,3],[4,5,6],[7,8,9]] and try to figure out a way to solve this problem. ...
