ZeroJudge H659: Taxi

The operating hours of a taxi company in a certain area are from 7:00 in the morning to 23:00. Their fare calculation method is as follows:

• Within the first 2 kilometers of the journey, the fare is $20. For each additional kilometer after the initial 2 kilometers, an additional $5 is charged.
• For every 2 minutes of waiting time, an additional $5 is charged.
• If the taxi ride spans from 6:00 PM to 11:00 PM, the additional fare for each time is as follows:

Given the "total kilometers traveled, vehicle delay time, passenger boarding time, and disembarking time", please help calculate the total fare for the ride.

Thought Process

預設答案為 20，將 K -= 2 後如果 K > 0 就將答案 += K * 5，之後再將答案 += W / 2 * 5。

宣告一個 Map<int, int>，Key 值存夜間時間的「開始」，Value 存對應的價錢。跑一個 For迴圈 從 S 到 E-1，將答案 += Map[目前跑到的小時]。

Sample Code－ZeroJudge H659: Taxi

#include <iostream>
#include <map>
using namespace std;

int main() {
    cin.sync_with_stdio(0);
    cin.tie(0);
    int K, W, S, E, ans = 20;
    cin >> K >> W >> S >> E;
    K -= 2;
    if (K > 0) ans += K * 5;
    ans += W / 2 * 5;
    map<int, int>MAP;
    MAP[18] = 185;
    MAP[19] = 195;
    MAP[20] = 205;
    MAP[21] = 215;
    MAP[22] = 225;
    for (int i = S; i<E; i++) {
        ans += MAP[i];
    }
    cout << ans << "\n";
}
