CCF CSP刷题—小明上学

和《小明放学》不同的是小明实现并不知道红绿灯情况。
代码：

#include<iostream>
using namespace std;

int main() {
	long long r = 0;
	long long y = 0;
	long long g = 0;
	cin >> r >> y >> g;
	long long total = r + y + g;
	int n = 0;
	cin >> n;
	long long ** info = new long long*[n];
	for (int i = 0; i < n; i++)
		info[i] = new long long[2];

	long long totaltime = 0;
	for (int i = 0; i < n; i++) {
		cin >> info[i][0] >> info[i][1];
	}
	for (int i = 0; i < n; i++) {
		if (info[i][0] == 0) {
			totaltime += info[i][1];
		}
		else if (info[i][0] == 1) {
			totaltime += info[i][1];
		}
		else if (info[i][0] == 2) {
			totaltime += info[i][1] + r;
		}
		else if (info[i][0] == 3) {
		}
	}
	cout << totaltime << endl;
	system("pause");
	return 0;
}
