概述
https://leetcode-cn.com/problems/cong-wei-dao-tou-da-yin-lian-biao-lcof/
直接法
这里要注意直接在向量的前部插入性能比较差。
class Solution {
public:
    vector<int> reversePrint(ListNode* head) {
        vector<int> res;
        while (head != nullptr) {
            res.push_back(head->val);
            head = head->next;
        }
        reverse(res.begin(), res.end());
        return res;
    }
};
