    1292 - Maximum Side Length of a Square with Sum Less than or Equal to Threshold.

    Medium

    Given a m x n matrix mat and an integer threshold, return the maximum side-length of a square with a sum less than or equal to threshold or return 0 if there is no such square.

    Example 1:

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

    Output: 2

    Explanation: The maximum side length of square with sum less than 4 is 2 as shown.

    Example 2:

    Input: mat = [[2,2,2,2,2],[2,2,2,2,2],[2,2,2,2,2],[2,2,2,2,2],[2,2,2,2,2]], threshold = 1

    Output: 0

    Constraints:

    • m == mat.length
    • n == mat[i].length
    • 1 <= m, n <= 300
    • 0 <= mat[i][j] <= 104
    • 0 <= threshold <= 105
