本文介绍了一个用于计算接力赛跑平均速度的程序实现。该程序能够处理多达20个赛段的比赛，并能正确处理运动员被取消资格的情况。文章通过示例输入和输出展示了如何使用该程序。

昨天家里来了几个小朋友，和我抢电脑，我输了，

今天在其拳打脚踢的情况下艰难的AC了

这道题主要要解决的是输入输出的格式控制，还有一个舍入问题

不说了，贴个代码，电脑让他

Problem Description

A relay is a race for two or more teams of runners. Each member of a team runs one section of the race. Your task is to help to evaluate the results of a relay race.

You have to process several teams. For each team you are given a list with the running times for every section of the race. You are to compute the average time per kilometer over the whole distance. That's easy, isn't it?
So if you like the fun and challenge competing at this contest, perhaps you like a relay race, too. Students from Ulm participated e.g. at the "SOLA" relay in Zurich, Switzerland. For more information visit http://www.sola.asvz.ethz.ch/ after the contest is over.

Input

The first line of the input specifies the number of sections n followed by the total distance of the relay d in kilometers. You may safely assume that 1 <= n <= 20 and 0.0 < d < 200.0. Every following line gives information about one team: the team number t (an integer, right-justified in a field of width 3) is followed by the n results for each section, separated by a single space. These running times are given in the format "h:mm:ss" with integer numbers for the hours, minutes and seconds, respectively. In the special case of a runner being disqualified, the running time will be denoted by "-:--:--". Finally, the data on every line is terminated by a newline character. Input is terminated by EOF.

Output

For each team output exactly one line giving the team's number t right aligned in a field of width 3, and the average time for this team rounded to whole seconds in the format "m:ss". If at least one of the team's runners has been disqualified, output "-" instead. Adhere to the sample output for the exact format of presentation.

Sample Input

12.5
0:23:21 0:25:01
0:23:32 -:--:--
0:33:20 0:41:35

Sample Output

3:52 min/km
-
6:00 min/km

#include<iostream>
using namespace std;
int n, t, *m, *s,sign,time,speed;
char *h;
double d;


void input()
{
	for (int i = 0; i < n; i++)
	{
		cin >> h[i];
		if (h[i] == '-')
		{
			sign = 1;
			for (int j = 0; j < 6; j++)
				cin.get();
		}
		else
		{
			time += ((int)h[i] - 48) * 60 * 60;
			cin.get();
			cin >> m[i];
			time += m[i] * 60;
			cin.get();
			cin >> s[i];
			time += s[i];
		}
	}
}

void output()
{
	if (t >= 0 && t <= 9)
		cout << "  " << t << ": ";
	else if (t > 9 && t <= 99)
		cout << ' ' << t << ": ";
	else
		cout << t << ": ";
	if (sign == 0)
	{
		speed = time / d;
		if (time / d - speed >= 0.5)
			speed++;
		cout << speed / 60 << ':';
		if (speed % 60 >= 0 && speed % 60 <= 9)
			cout << '0' << speed % 60 << " min/km" << endl;
		else
			cout << speed % 60 << " min/km" << endl;
	}
	else
		cout << "-\n";
}
int main(void)
{
	cin >> n >> d;
	h = new char[n];
	m = new int[n];
	s = new int[n];	
	while (cin>>t)
	{
		sign = 0;
		time=0;
		input();
		output();
	}
	return 0;
}
