示例 1:
输入:head = [1,3,2]
输出:[2,3,1]
输出:[2,3,1]

vector的插入字符是push_back,结点的数据是用->,reverse是algorithm中的算法可以直接反转
1 class Solution { 2 public: 3 vector<int> res; 4 vector<int> reversePrint(ListNode* head) { 5 while(head) 6 { 7 res.push_back(head->val); 8 head=head->next; 9 } 10 reverse(res.begin(),res.end()); 11 return res; 12 } 13 };
