1329. Sort the Matrix Diagonally Medium
1/**
2 * [1329] Sort the Matrix Diagonally
3 *
4 * A matrix diagonal is a diagonal line of cells starting from some cell in either the topmost row or leftmost column and going in the bottom-right direction until reaching the matrix's end. For example, the matrix diagonal starting from mat[2][0], where mat is a 6 x 3 matrix, includes cells mat[2][0], mat[3][1], and mat[4][2].
5 * Given an m x n matrix mat of integers, sort each matrix diagonal in ascending order and return the resulting matrix.

9 * Input: mat = [[3,3,1,1],[2,2,1,2],[1,1,1,2]]
10 * Output: [[1,1,1,1],[1,2,2,2],[1,2,3,3]]
11 *
12 * Example 2:
13 *
14 * Input: mat = [[11,25,66,1,69,7],[23,55,17,45,15,52],[75,31,36,44,58,8],[22,27,33,25,68,4],[84,28,14,11,5,50]]
15 * Output: [[5,17,4,1,52,7],[11,11,25,45,8,69],[14,23,25,44,58,15],[22,27,31,36,50,66],[84,28,75,33,55,68]]
16 *
17 *
18 * Constraints:
19 *
20 * m == mat.length
21 * n == mat[i].length
22 * 1 <= m, n <= 100
23 * 1 <= mat[i][j] <= 100
