简单的输入输出，看代码即可

struct tree
{
    int var;
    struct tree* next;
};

#define NULL 0

int main()
{
    int n,i;
    struct tree* head = (struct tree *)malloc(sizeof(struct tree));
    struct tree* tmp;
    struct tree* tail;
    scanf("%d\n", &n);
    int* a = (int *)malloc(sizeof(int)*n);
    int* b = (int *)malloc(sizeof(int)*n);
    for(i=0; i<n; i++)
    {
        scanf("%d",&a[i]);
    }
    for(i=0; i<n; i++)
    {
        scanf("%d",&b[i]);
        b[i] += a[i];
    }
    head->var = b[0];
    head->next = NULL;
    tail = head;
    for(i=1; i<n; i++)
    {
        tmp = (struct tree *)malloc(sizeof(struct tree));
        tmp->var = b[i];
        tmp->next = NULL;
        tail->next = tmp;
        tail = tail->next;
    }
    while(head != NULL)
    {
        printf("%d ", head->var);
        head = head->next;
    }
    return 0;
}
