1267. 统计参与通信的服务器
题意:
同行同列可以发生通信,求能发生通信的机器数量
解:
标记每行/每列的机器个数即可
实际代码:
#include<bits/stdc++.h>
using namespace std;
class Solution {
public:int countServers(vector<vector<int>>& grid) {int row=grid.size(),col=grid[0].size();vector<int>rowNum(row),colNum(col);for(int i=0;i<row;i++){for(int j=0;j<col;j++){if(grid[i][j]){rowNum[i]++;colNum[j]++;}}}int ans=0;for(int i=0;i<row;i++){for(int j=0;j<col;j++){if((grid[i][j])&&(rowNum[i]>1||colNum[j]>1)) ans++;}}return ans;}
};
int main()
{Solution solution;
}
限制:
m == grid.length
n == grid[i].length
1 <= m <= 250
1 <= n <= 250
grid[i][j] == 0 or 1
