Answer 1

#include <stdio.h>
#include <stdlib.h>

int inverse(int n);
int main()
{
    int n;
    scanf("%d",&n);
    while( n != inverse(n))
    {
        printf("%d ",n);
        n += inverse(n);
    }
    printf("%d ",n);//最后一个数字需要补上
    return 0;
}
int inverse(int n)
{
    int a,b;
    a = 0;
    b = 0;
    while( n != 0)
    {
        a = n%10;
        b = (a+b)*10;
        n = n/10;
    }
    b /= 10;
    return b;
}
