使用拉链法哈希表插入失败

这里用的是尾插法，数组默认为NULL；

const int MaxSize = 101;
Node<int> *ARR[MaxSize];
//使用拉链法解决散列冲突
void Insert(int data) {
    if (ARR[data]==NULL) {
        Node<int> * s = new Node<int>;
        s->data = data;
        ARR[data] = s;
        s->next = NULL;
    }
    else {
        while (ARR[data]) {
            ARR[data] = ARR[data]->next;
        }
            Node<int> * s = new Node<int>;
            s->data = data;
            ARR[data] = s;
            s->next = NULL;
    }

}
//附上一段简单的测试代码
int main() {
    int a[10] = { 1,5,6,7,8,9,10,12,14,5};
    std::cout << ARR[5]->next->data;
