POJ1207-The 3n + 1 problem

http://poj.org/problem?id=1207

注意輸入兩個數的大小，水。。。

#include <stdio.h>
int main(void)
{int a,b,m,count,i,max;while(scanf("%d%d",&a,&b)!=EOF){printf("%d %d ",a,b);if(a>b){m=a;a=b;b=m;}max=0;for(i=a;i<=b;i++){m=i;count=1;while(m!=1){if(m%2)m=3*m+1;elsem/=2;count++;}if(count>max)max=count;}printf("%d\n",max);}return 0;
}
