天是来自LeetCode的第2题:两数相加(Add Two Numbers) 注意:这里说的两数字,是来自两个非空的链表,而不是简单的加法运算哦。 No2. 两数相加(Add Two Numbers) 题目: 给你两个 非空 的链表,表示两个非负的整数。它们每位数字都是按照 逆序 的方式存储的,并且每个节点只能存储 一位 数字。 请你将两个数...
代码(Python3) # Definition for singly-linked list. # class ListNode: # def __init__(self, val=0, next=None): # self.val = val # self.next = next class Solution: def addTwoNumbers(self, l1: Optional[ListNode], l2: Optional[ListNode]) -> Optional[ListNode]: # 哨兵结点,方便后续处...
https://leetcode.com/problems/add-two-numbers/ 题意分析: 这道题目是要将两个单链条相加。输出得到的新链条。 题目思路: 不难发现,其实题目就是要我们模拟加法的实现。那么,我们就直接从低位(链条第一位)开始,同位相加,满10就往高位+1。 代码(python): View Code PS:要注意的是,不要忘记最后的那个+1...
