1329 - Sort the Matrix Diagonally\. Medium 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]`. Given an `m x n` matrix `mat` of integers, sort each **matrix diagonal** in ascending order and return _the resulting matrix_. **Example 1:**  **Input:** mat = \[\[3,3,1,1],[2,2,1,2],[1,1,1,2]] **Output:** [[1,1,1,1],[1,2,2,2],[1,2,3,3]] **Example 2:** **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]] **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]] **Constraints:** * `m == mat.length` * `n == mat[i].length` * `1 <= m, n <= 100` * `1 <= mat[i][j] <= 100`
