풀이

int 범위...!!!

코드

#include <vector>
#include <iostream>

using namespace std;

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

	int N, B, C;
	vector<int> room;
	long long ans = 0;

	cin >> N;
	for (int i = 0; i < N; i++) {
		int tmp;
		cin >> tmp;
		room.push_back(tmp);
	}
	cin >> B >> C;

	for (int i = 0; i < room.size(); i++) {
		room[i] -= B;
		ans++;
	}
	for (int i = 0; i < room.size(); i++) {
		if (room[i] > 0) {
			ans += room[i] / C;
			if (room[i] % C != 0)	ans++;
		}
	}

	cout << ans;

	return 0;
