题目标签:Linked List 题目给了我们两个 数字的linked list,让我们把它们相加,返回一个新的linked list. 因为题目要求不能 reverse,可以把 两个list 的数字都 存入 两个stack.利用了stack的特性,就可以从后面把数字相加,具体看code. Java Solution: Runtime:  6 ms, faster than 51.06% Memory Usage: 45.4 MB, less than 64.71% 完成日期:07/08/201…

题意:两个非空链表求和,这两个链表所表示的数字没有前导零,要求不能修改原链表,如反转链表. 分析:用stack分别存两个链表的数字,然后从低位开始边求和边重新构造链表. Input: (7 -> 2 -> 4 -> 3) + (5 -> 6 -> 4) Output: 7 -> 8 -> 0 -> 7 /** * Definition for singly-linked list. * struct ListNode { * int val; * ListN…

Question 445. Add Two Numbers II Solution 题目大意:两个列表相加 思路:构造两个栈,两个列表的数依次入栈,再出栈的时候计算其和作为返回链表的一个节点 Java实现: public ListNode addTwoNumbers(ListNode l1, ListNode l2) { Stack<Integer> s1 = new Stack<>(); Stack<Integer> s2 = new Stack<>();…
