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<>();…

给定两个非空链表来表示两个非负整数.位数按照逆序方式存储,它们的每个节点只存储单个数字.将两数相加返回一个新的链表. 你可以假设除了数字 0 之外,这两个数字都不会以零开头. 示例: 输入:(2 -> 4 -> 3) + (5 -> 6 -> 4) 输出:7 -> 0 -> 8 原因:342 + 465 = 807 # Definition for singly-linked list. # class ListNode(object): # def __init__(…
