2. Add Two Numbers——Python 题目: You are given two linked lists representing two non-negative numbers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two numbers and return it as a linked list....
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。
先实例一个头结点,然后在 while 循环中逐个加入节点 del ret 删除头结点 代码实现: classListNode:def__init__(self, x): self.val=x self.next=NoneclassSolution:#@return a ListNodedefaddTwoNumbers(self, l1, l2):ifl1isNone:returnl2elifl2isNone:returnl1else: ...
Python 代码如下: # Definition for singly-linked list. # class ListNode(object): # def __init__(self, val=0, next=None): # self.val = val # self.next = next class Solution(object): def addTwoNumbers(self, l1, l2): st1 = [] ...
The array module is useful when you need to create an array of integers and floating-point numbers. The NumPy module is useful when you need to do mathematical operations on an array. In many cases, you can use List to create arrays because List provides flexibility, such as mixed data ...
