1267번: 핸드폰 요금

간단한 구현문제다.

#include <iostream>

using namespace std;

int n;
int arr[21];

int main()
{
	ios::sync_with_stdio(0);
	cin.tie(0);
	cout.tie(0);

	cin >> n;
	for (int i = 0; i < n; i++) {
		cin >> arr[i];
	}
	int y = 0, m = 0;
	for (int i = 0; i < n; i++) {
		int a = arr[i];
		while (a >= 0) {
			a -= 30;
			y += 10;
		}
		a = arr[i];
		while (a >= 0) {
			a -= 60;
			m += 15;
		}
	}
	if (y < m) cout << "Y " << y << endl;
	else if (y > m) cout << "M " << m << endl;
	else cout << "Y M " << y << endl;
}

전체코드다.
