    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
