Problem Statement

Given a 2D matrix of size m x n, return a 1D array containing elements of the matrix in the diagonal order.

Example 1:

  • Input: `matrix =
[[1,2,3],
 [4,5,6]]
  • Expected Output: [1,2,4,5,3,6]
  • Justification: Traversal begins at 1, moves to 2, diagonally down to 4, up to 5, down to 3, and finally to 6.

Example 2:

  • Input: matrix =
[[1,5],
 [3,6]]
  • Expected Output: [1,5,3,6]
  • Justification: The traversal starts from 1, moves to 2, then down to 3, and finally to 4.

Example 3:

  • Input: `matrix =
[[1],
 [2],
 [3]]
  • Expected Output: [1,2,3]
  • Justification: The traversal is straightforward down the single-column matrix.
