Codeforces//Good Bye 2013//A. New Year Candles 水题

第一次在Codeforces上提交题，全是英文，啊。应该是场比赛，WA了两次，丫的。哎，什么时候才能不做水题了呢。Happy New Year！Zhou Ping！努力奋斗！

题目链接：A. New Year Candles

题目大意：输入两个数a和b，用b个燃烧完的蜡烛可以换一个新的蜡烛，以此类推。

比如一共有4个蜡烛，2个蜡烛可以换一个新的蜡烛。4个蜡烛可以换2个新的蜡烛，2个新蜡烛燃烧后仍可以换1个蜡烛，所以一共可以燃烧4+2+1=7个蜡烛。

例： 4 2 4/2 2 2/2 1 例： 6 3 6/3 2 一直到余数小于b结束。

# include <stdio.h>
int main()
{int a,b,c=0,num=0;scanf("%d %d",&a,&b);while(1){num=num+a;c=c+a;a=c/b;if(c<b)break;c=c%b;}printf("%d\n",num);return 0;
}
