这个怎么写啊，求解求解？！

#include <stdio.h>
int main()
{
    int n,t,s=0;
    scanf("%d",&n);
    t = n;
    while(t)
    {
        s = s*10 + t%10;
        t/=10;
    }
    printf("%d",n+s);
    return 0;
}

供参考：

#include <stdio.h>
int main()
{
    int n, k, s = 0;
    scanf("%d", &n);
    k = n;
    while (k)
    {
        s = s * 10 + k % 10;
        k /= 10;
    }
    printf("%d", s += n);
    return 0;
}
