1、挺简单的题目，模拟即可，注意sscanf的使用。

#include <stdio.h>
int main(void)
{
    int n,i,j,a[10010]={0},b[10010]={0};
    char s[100000]="";
    while(scanf("%d",&n)==1)
    {
        char*p;
        int t;
        getchar();
        fgets(s,100000,stdin);
        p=s;
        j=0;
        while(sscanf(p,"%d%n",&a[j],&t)==1)
        {
            j++;
            p+=t;
        }
        n*=-1;
        for(i=0;i<j-1;i++)
        {
            a[i+1]-=a[i]*n;
            b[i]=a[i];
        }
        printf("q(x):");
        for(i=0;i<j-1;i++)
             printf(" %d",b[i]);
        printf("\n");
        printf("r = %d\n\n",a[j-1]);
    }
     return 0;
}
