很简单的一道题，不过一直wa，之后才发现原来0应该用10表示！！！郁闷！！！

 

#include<stdio.h> #include<stdlib.h> int main() {     int n,m,i,j,sum[100],total;     scanf("%d",&n);     m = n;     if (n == 0)        printf("10\n");     else     if (n == 1)        printf("1\n");     else     {              total = 0;         for (i = 9;i > 1;i--)         {             while(m % i == 0)             {                     sum[total] = i;                     total++;                     m /= i;             }         }         if (m != 1)            printf("-1\n");         else         {             for (i = total-1;i >=0;i--)                  printf("%d",sum[i]);             printf("\n");         }     }     // system("Pause");     return 0; }
