纯模拟题，很简单

#include <bits/stdc++.h>
using namespace std;
#define ll long long
ll n,x,y;
int main(){
    cin>>n>>x>>y;
    for (int i=1;i<=n;i++){
        printf("(%d,%d) ",x,i);
    }
    cout<<endl;
    for (int i=1;i<=n;i++){
        printf("(%d,%d) ",i,y);
    }
    cout<<endl;
    for (int i=1-min(x,y);i<=n-max(x,y);i++){//有点复杂
        printf("(%d,%d) ",x+i,y+i);
    }
    cout<<endl;
    for (int i=max(1-y,x-n);i<=min(x-1,n-y);i++){//更复杂
        printf("(%d,%d) ",x-i,y+i);
    }
    cout<<endl;
    return 0;
}
