Examples
Example 1
Input
- matrix =
[[ 5, 0, 0, 5, 8],
[ 9, 8,10, 3, 9],
[ 0, 7, 2, 3, 1],
[ 8, 0, 6, 7, 2],
[ 4, 1, 8, 5,10]]
Output
- answer =
[[0, 0, 0, 0, 0], [0, 0, 0, 3, 9], [0, 0, 0, 0, 0], [0, 0, 0, 0, 0], [0, 0, 0, 5, 10]]
Explanation
These rows contain a 0
: [0, 2, 3]
and the returned matrix contains 0
in those rows.
These columns contain a 0
: [0, 1, 2]
and the returned matrix contains 0
in those columns.
