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], wherematis a6 x 3matrix, includes cellsmat[2][0],mat[3][1], andmat[4][2].Given an
m x nmatrixmatof 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.lengthn == mat[i].length1 <= m, n <= 1001 <= mat[i][j] <= 100
