Given an m x n
integer matrix matrix
, if an element is 0
, set its entire row and column to 0
's.
You must do it in place.
๐ฅ๏ธ Input: matrix = [[1,1,1],[1,0,1],[1,1,1]]
๐จ๏ธ Output: [[1,0,1],[0,0,0],[1,0,1]]
๐ฅ๏ธ Input: matrix = [[0,1,2,0],[3,4,5,2],[1,3,1,5]]
๐จ๏ธ Output: [[0,0,0,0],[0,4,5,0],[0,3,1,0]]
m == matrix.length
n == matrix[0].length
1 <= m, n <= 200
-2^31 <= matrix[i][j] <= 2^31 - 1
A straightforward solution using O(mn)
space is probably a bad idea.
A simple improvement uses O(m + n)
space, but still not the best solution.
Could you devise a constant space solution? ๐ค
