Question

Answer 1

供参考：

#include<stdio.h>
int main()
{
    int T,n,k,flg=0;
    scanf("%d",&T);
    while(T !=1 && T != 145)
    {
        n = 0;k = 0;flg++;
        printf("%d-",T);
        while(T)
        {
             n += (T%10)*(T%10);
             printf("%c%d*%d",k++==0?'>':'+',T%10,T%10);
             T /= 10;
        }
        printf("=%d\n",n);
        T = n;
    }
    if(flg == 0)printf("%d",T);
 
    return 0;
}
