Spiral Matrix · Coding Interview Practice

Spiral MatrixGiven an m x n matrix, return all elements in spiral order.Constraints

m == matrix.length, n == matrix[i].length

1 <= m, n <= 10

-100 <= matrix[i][j] <= 100

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]
