Original link ： The finger of the sword Offer 06. Print linked list from end to end

solution:

Traverse side linked list , Save node values in an array , Last reverse. Time complexity O(n)

class Solution {
public:
    vector<int> reversePrint(ListNode* head) {
        vector<int> res;
        ListNode *cur = head;
        while(cur != NULL) {
            res.push_back(cur->val);
            cur = cur->next;
        }        
        reverse(res.begin(),res.end());
        return res;
    }
};
