注意A+B=0的特殊情况

#include <stdio.h>#include <math.h>  long long int a,b,sum;int m,s[1000],begin,i;int main(){while(~scanf("%d",&m)){if(m == 0) break;begin = 0;scanf("%lld%lld",&a,&b);sum = a + b;if(sum == 0){printf("%d\n",0);continue;}while(sum){s[begin++] = sum % m;sum /= m;}begin--;for(i = begin; i >= 0; i--)printf("%d",s[i]);printf("\n");}}
