    54 - Spiral Matrix.

    Medium

    Given an m x n matrix, return all elements of the matrix in spiral order.

    Example 1:

    Input: matrix = [[1,2,3],[4,5,6],[7,8,9]]

    Output: [1,2,3,6,9,8,7,4,5]

    Example 2:

    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
