#include <bits/stdc++.h>
using namespace std;
#define ll long long
#define pb push_back

const int N=1e6+5;
int n;
ll R,r;
vector<int> ans;

struct Nod{
  ll x,y;
  int id;
  bool operator <(const Nod &a) const{return x*x+y*y<a.x*a.x+a.y*a.y;}
}a[N];

ll Len(Nod a){return a.x*a.x+a.y*a.y;}

void SOLVE(){
  cin>>n>>R>>r;
  for(int i=1;i<=n;i++) cin>>a[i].x>>a[i].y,a[i].id=i;
  sort(a+1,a+n+1);

  ans.clear();
  
  R-=r;
  int len=1;
  while(len<=n&&(R-r)*(R-r)>=Len(a[len])) ++len;
  if(len>1) for(int i=1;i<len;i++) ans.pb(a[i].id);
  else for(int i=1;i<=n;i++) if(Len(a[i])==Len(a[1])) ans.pb(a[i].id);

  sort(ans.begin(),ans.end());
  cout<<(int)ans.size()<<'\n';
  for(int i=0;i<(int)ans.size();i++) cout<<ans[i]<<(i==(int)ans.size()-1?'\n':' ');
}

int main(){
  ios::sync_with_stdio(false);cin.tie(0);cout.tie(0);
  int _;cin>>_;
  while(_--) SOLVE();
  return 0;
}

这程序好像有点Bug,我给组数据试试?
