Doubt in question

#1

If one circle is completely contained in the other circle, will it be counted as overlapping?

#2

@tilakparth123
yes for this problem ,you can consider them as overlapping

#3

My code has passed 5 test cases and failed in one can you pls point out the error

#4

#include <bits/stdc++.h>
using namespace std;

bool compare(pair<int,int> p1, pair<int,int> p2){
return p1.second<p2.second;
}

int main() {
ios_base::sync_with_stdio(false);
cin.tie(NULL);

    // your code goes here
    int n; cin>>n;
    vector<pair<int,int>> v;
    int startp,endp;
	int c,r;
    for(int i=0;i<n;i++){
        cin>>c>>r;
		startp=c-r;
		endp=c+r;
        v.push_back(make_pair(startp,endp));
       // cout<<v[i].first<<" "<<v[i].second<<endl;
    }
    sort(v.begin(),v.end(),compare);
   // for(int i=0;i<n;i++)cout<<v[i].first<<" "<<v[i].second<<endl;
    int ans=1;
    endp =v[0].second;
   // cout<<endp<<endl;
    for(int i=1;i<n;i++){
        if(v[i].first>endp){
            endp=v[i].second;
            ans++;
        }
    }
    cout<<n-ans;
return 0;
