[LeetCode]题解(python):002-Add Two Numbers 题目来源: 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(p...
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...

2. Add Two Numbers 两数相加 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。

Add Two Numbers with User InputIn this example, the user must input two numbers. Then we print the sum by calculating (adding) the two numbers:Example x = input("Type a number: ")y = input("Type another number: ")sum = int(x) + int(y)print("The sum is: ", sum) Try it ...
