Hey guys..C++ solution

int main() {

long long n; cin>>n; vectora(n); for(long long i=0; i>a[i];

long long q; cin>>q; for(int i=0; i>x;

auto it=lower_bound(a.begin(),a.end(),x);
long long index=it - a.begin();

if(it!=a.end() && *it==x)
{
    cout<<"Yes"<<" "<<index+1<<endl;
}
else 
{
  cout<<"No"<<" "<<index+1<<endl;
}

}

}
