This is a solution to Hackerrank's algorithm problem Implementation of the same problem in C++ is as following. #include #include #include #include #include using namespace std; int main() { int age_n; std::vector candles_n; int input; cin>>age_n; while(cin >> input) candles_n.push_back(input); int largest_height = *std::max_element(candles_n.begin(), candles_n.end()); int mycount = std::count (candles_n.begin(), candles_n.end(), largest_height); cout << mycount; return 0; }
