CCF CSP 201512-2：消除类游戏

代码如下：

#include <bits/stdc++.h>

using namespace std;

//消除游戏
int main(){
int n, m;
cin >> n >> m;
vector< vector<int> > v(n, vector<int>(m));
for(int i = 0; i < n; i++){
for(int j = 0; j < m; j++){
cin >> v[i][j];
}
}

vector< pair<int, int> > index;
for(int i = 0; i < n; i++){
for(int j = 0; j < m - 2; j++){
if(v[i][j] == v[i][j+1] && v[i][j+1] == v[i][j+2]){
index.push_back(pair<int, int>(i, j));
index.push_back(pair<int, int>(i, j+1));
index.push_back(pair<int, int>(i, j+2));
}
}
}

for(int j = 0; j < m; j++){
for(int i = 0; i < n - 2; i++){
if(v[i][j] == v[i+1][j] && v[i+1][j] == v[i+2][j]){
index.push_back(pair<int, int>(i, j));
index.push_back(pair<int, int>(i+1, j));
index.push_back(pair<int, int>(i+2, j));
}
}
}
for(int i = 0; i < index.size(); i++){
int a = index[i].first, b = index[i].second;
v[a][b] = 0;
}

for(int i = 0; i < n; i++){
for(int j = 0; j < m; j++){
cout << v[i][j] << " ";
}
cout << endl;
}
return 0;
}
