    498 - Diagonal Traverse.

    Medium

    Given an m x n matrix mat, return an array of all the elements of the array in a diagonal order.

    Example 1:

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

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

    Example 2:

    Input: mat = \[\[1,2],3,4]

    Output: 1,2,3,4

    Constraints:

    • m == mat.length

    • n == mat[i].length

    • <code>1 <= m, n <= 10<sup>4</sup></code>

    • <code>1 <= m * n <= 10<sup>4</sup></code>

    • <code>-10<sup>5</sup><= matj<= 10<sup>5</sup></code>
