这道题是LeetCode里的第2道题. 题目要求: 给出两个 非空 的链表用来表示两个非负的整数.其中,它们各自的位数是按照 逆序 的方式存储的,并且它们的每个节点只能存储 一位 数字. 如果,我们将这两个数相加起来,则会返回一个新的链表来表示它们的和. 您可以假设除了数字 0 之外,这两个数都不会以 0 开头. 示例: 输入:(2 -> 4 -> 3) + (5 -> 6 -> 4) 输出:7 -> 0 -> 8 原因:342 + 465 = 807 这道题的条件判断…

题目描述: 解题思路: 给定两个链表(代表两个非负数),数字的各位以正序存储,将两个代表数字的链表想加获得一个新的链表(代表两数之和). 如(7->2->4->3)(7243) + (5->6->4)(564) = (7->8->0->7)(7807) 此题与[LeetCode2]Add Two Numbers解决思路类似,不同之处在于此题的数字以正序存储,故需要借助栈. Java代码: import java.util.Stack; //public cl…
