这道题可以直接用for循环直接做。
AC记录```c
#include<bits/stdc++.h>
using namespace std;
const int N=100;
typedef long long ll;
struct qwe{
int x,y;
};
int main(){
int n,m,aa,b,minn,xx,yy;
scanf("%d%d%d%d",&n,&m,&aa,&b);
qwe a[aa+1];
for(int i=1;i<=aa;i++){
scanf("%d%d",&a[i].x,&a[i].y);
}
for(int i=1;i<=b;i++){
minn=2100000000;
scanf("%d%d",&xx,&yy);
for(int j=1;j<=aa;j++){
minn=min(minn,abs(xx-a[j].x)+abs(yy-a[j].y));
}
printf("%d\n",minn);
}
return 0;
}
