UVA 694-The Collatz Sequence

奇怪啊一开始int一直TLE后来改成long就AC了 难道是uva环境的问题 求解。。。

#include<stdio.h>int cnt=1;long A,limit,tmp,ans;int main(){   while(~scanf("%ld%ld",&A,&limit)&&limit!=-1)    {   ans=0;        if(A==1)break;        tmp=A;        for(;;)        {            if(!(A&1))  {A/=2;ans++;}            else    {A=3*A+1;ans++;}            if(A>limit)break;            if(A==1) {ans++;break;}        }        printf("Case %d: A = %ld, limit = %ld, number of terms = %ld\n",cnt,tmp,limit,ans);        cnt++;    }   return 0;}
