666,考级时被这题搞蒙了，出来做对了

暴力枚举就行，四级怕是考不过了。。。

#include <bits/stdc++.h>
using namespace std;
int vis[1100][1100];
int main(){
	int n,m,t;
	cin >> n >> m >> t;
	for(int i = 1;i <= t;i++){
		int a,b;
		cin >> a >> b;
		vis[a][b] = 1;
	}
	for(int i = 1;i <= n;i++){
		for(int j = 1;j <= m;j++){
			int cnt = 0;
			if(vis[i][j] != 1){
				if(1 == vis[i-1][j])cnt++;
				if(1 == vis[i][j-1])cnt++;
				if(1 == vis[i+1][j])cnt++;
				if(1 == vis[i][j+1])cnt++;
				if(1 == vis[i+1][j-1])cnt++;
				if(1 == vis[i-1][j+1])cnt++;
				if(1 == vis[i-1][j-1])cnt++;
				if(1 == vis[i+1][j+1])cnt++;
				cout<<cnt<<" ";
			}
			else cout<<"* ";
		}
		cout<<endl;
	}
	return 0;
}
