#include<iostream>
#include<cstring>
#include<vector>
using namespace std;
using LL = long long;
int main(){
#ifdef LOCAL
freopen("data.in", "r", stdin);
freopen("data.out", "w", stdout);
#endif
cin.tie(0);
cout.tie(0);
ios::sync_with_stdio(0);
int T;
cin >> T;
while(T--){
int n, R, r;
cin >> n >> R >> r;
R -= r;
LL t = (R - r) * (R - r);
LL mn = 1e18;
vector<int> ans;
for(int i = 0; i < n; i++){
LL x, y;
cin >> x >> y;
LL d2 = x * x + y * y;
if (d2 <= t){
d2 = -1;
}
if (d2 < mn){
ans = {i + 1};
mn = d2;
}
else if (d2 == mn){
ans.push_back(i + 1);
}
}
cout << ans.size() << '\n';
for(int i = 0; i < ans.size(); i++){
cout << ans[i] << " \n"[i + 1 == ans.size()];
}
}
}
这程序好像有点Bug,我给组数据试试?
