I Dont know why everyone is confusing, the most simplest answer..

int main() { /* Enter your code here. Read input from STDIN. Print output to STDOUT */ int n ; cin >> n; vectornums(n); for(int i = 0;i> nums[i]; }

int q;
cin >> q;
while(q--)
{
    int target;
    cin >> target;
    auto it = lower_bound(nums.begin(),nums.end(),target);
    if(*it == target)
    {
        cout << "Yes " <<  it-nums.begin()+1 << endl;
    }
    else {
        cout << "No " << it-nums.begin()+1<<endl;
    }
}
return 0;

}
