函数的调用666

解题思路:

注意事项:

参考代码:

#include <stdio.h>

int happy(int n)

{

        int nn=n,num=0,sum=0,i;

        while(nn>0)

        {

                nn=nn/10;

                num++;

        }

        for(i=0;i<num/2;i++)

        {

                sum=sum*10+n%10;

                n=n/10;

        }

        if((num%2!=0&&sum==n/10)||(num%2==0&&sum==n))return 1;

        return 0;

}

int fun(int n,int game)

{

        int sum=0,nn=n;

        while(n>0)

        {

                sum=sum*10+n%10;

                n=n/10;

        }

        nn=nn+sum;

        if(happy(nn))

        {

                game++;

                printf("%d\n",game);

        }

        else

        {

                game++;

                if(game>8)

                {

                        printf("0\n");

                        return 0;

                }

                fun(nn,game);

        }

}

int main()

{

        int n;

        scanf("%d",&n);

        while(n--)

        {

                int m,game=0;

                scanf("%d",&m);

                fun(m,game);

        }

        return 0;

}
