直接做吧，没什么好说的了

#include<iostream>
using namespace std;

int main()
{
    int n,i,j;
    while(cin>>n>>i>>j)
    {
        int c;
        //Line
        for(c=1;c<=n;c++)
            cout<<'('<<i<<','<<c<<')';
        cout<<endl;
        //Row
        for(c=1;c<=n;c++)
            cout<<'('<<c<<','<<j<<')';
        cout<<endl;
        // '\'direction
        int t1=i,t2=j;
        while(t1>1 && t2>1) t1--,t2--;
        while(t1<=n && t2<=n) cout<<'('<<t1++<<','<<t2++<<')';
        cout<<endl;
        // '/'direction
        t1=i,t2=j;
        while(t1<n && t2>1) t1++,t2--;
        while(t1>0 && t2<=n) cout<<'('<<t1--<<','<<t2++<<')';
        cout<<endl;
    }
    return 0;
}
