解題心得

想了一下才想到如何判斷區間QQ

程式碼

#include<iostream>
using namespace std;

int main()
{
	int k, w, s, e, sum = 0;
	cin >> k >> w >> s >> e;

	if (k < 2)
		sum += 20;
	else
		sum += 20 + (k - 2) * 5;
	sum += (w / 2) * 5;
	bool time[24] = { false };
	for (int i = s; i <= e; i++)
		time[i] = true;

	if (time[18] && time[19]) sum += 185;
	if (time[19] && time[20]) sum += 195;
	if (time[20] && time[21]) sum += 205;
	if (time[21] && time[22]) sum += 215;
	if (time[22] && time[23]) sum += 225;
	cout << sum;
	return 0;
}
