Homer Simpson, a very smart guy, likes eating Krusty-burgers. It takes Homer m minutes to eat a Krusty- burger. However, there�s a new type of burger in Apu�s Kwik-e-Mart. Homer likes those too. It takes him n minutes to eat one of these burgers. Given t minutes, you have to find out the maximum number of burgers Homer can eat without wasting any time. If he must waste time, he can have beer.

Input

Input consists of several test cases. Each test case consists of three integers m, n, t (0 < m,n,t < 10000). Input is terminated by EOF.

Output

For each test case, print in a single line the maximum number of burgers Homer can eat without having beer. If homer must have beer, then also print the time he gets for drinking, separated by a single space. It is preferable that Homer drinks as little beer as possible.

Sample Input

3 5 54
3 5 55

Sample Output

题意：尽量用完时间t，求出最多吃多少个汉堡；如果实在用不完，再输出和啤酒的时间。

#include<stdio.h>
#include<string.h>
int main()
{
	int m,n,t,max,i;
	while(~scanf("%d%d%d",&m,&n,&t))
	{
		if(m>n) /*保证m>n*/
		{int temp=m;m=n;n=temp;}
		max=t/m; /*最多的数量*/
		int beer_time=t-max*m; /*喝啤酒的时间*/
		if(beer_time==0)
		{
			printf("%d\n",max);
			continue;
		}
		for(i=1;i<=t/n;i++) 
		{
			int temp_max=(t-n*i)/m+i;
			int temp_beer_time=t-((temp_max-i)*m+i*n);
            if(temp_beer_time>=0&&temp_beer_time<beer_time)
			{
				max=temp_max;
				beer_time=temp_beer_time;
			}
			if(temp_beer_time==0)
				break;
		}
		printf("%d",max);
		if(beer_time!=0)
			printf(" %d",beer_time);
		printf("\n");
	}
	return 0;
