程序代码：

#include"stdio.h"
int f_sum(int *c,int n)
{
    int i;
    if(c>(c-1)*(n-1))
    return 1;
    else
    f_sum(c-1,n-1)
    return 0;
}
int main()
{
    int c[100],n,i,nn;
    while(1)
    {
        for(i=0;i<10;i++)
        scanf("%d",&c[i]);
        scanf("%d",&n);
        printf("%d\n",f_sum(c,n));
    }
    return 0;
}
