#include <bits/stdc++.h>
using namespace std;
int x[110],y[110],p[110];
int d2(int i){return x[i]*x[i]+y[i]*y[i];}
int main() {
	std::ios::sync_with_stdio(0); cin.tie(0); cout.tie(0);
	int T;
	cin>>T;
	while(T--)
	{
		int n,R,r;
		cin>>n>>R>>r;
		for(int i=1;i<=n;i++) cin>>x[i]>>y[i];
		iota(p+1,p+n+1,1);
		sort(p+1,p+n+1,[](int i,int j){return d2(i)<d2(j);});
		int m=1;
		while(m<n && d2(p[m])==d2(p[m+1])) m++;
		while(m<n && d2(p[m+1])<=(R-2*r)*(R-2*r)) m++;
		sort(p+1,p+m+1);
		cout<<m<<"\n";
		for(int i=1;i<=m;i++) cout<<p[i]<<" \n"[i==m];
	}
	return 0;
}

这程序好像有点Bug,我给组数据试试?
