본문
Hard
3010150Add to ListShareGiven an m x n
matrix matrix
and an integer k
, return the max sum of a rectangle in the matrix such that its sum is no larger than k
.
It is guaranteed that there will be a rectangle with a sum no larger than k
.
Example 1:
Input: matrix = [[1,0,1],[0,-2,3]], k = 2 Output: 2 Explanation: Because the sum of the blue rectangle [[0, 1], [-2, 3]] is 2, and 2 is the max number no larger than k (k = 2).
Example 2:
Input: matrix = [[2,2,-1]], k = 3 Output: 3
Constraints:
m == matrix.length
n == matrix[i].length
1 <= m, n <= 100
-100 <= matrix[i][j] <= 100
-105 <= k <= 105
Follow up: What if the number of rows is much larger than the number of columns?
