Count Servers that Communicate
You are given a map of a server center, represented as an m * n integer matrix grid, where 1 means that on that cell there is a server and 0 means that it is no server. Two servers are said to communicate if they are on the same row or on the same column.
Return the number of servers that communicate with any other server.
Example 1
1 0 0 1
Input
grid = [[1,0],[0,1]]Output
0No servers can communicate with others.
Example 2
1 0 1 1
Input
grid = [[1,0],[1,1]]Output
3All three servers can communicate with at least one other server.
Constraints
- m == grid.length
- n == grid[i].length
- 1 <= m <= 250
- 1 <= n <= 250
- grid[i][j] == 0 or 1
