使用临时变量 Python 的元组解包 方法1:使用临时变量 这种方法需要一个临时变量来帮助交换两个元素。 # 使用临时变量交换元素my_list=[1,2,3,4]# 交换元素temp=my_list[0]# 取出第一个元素my_list[0]=my_list[2]# 把第三个元素赋值给第一个位置my_list[2]=temp# 把临时变量赋值给第三个位置print(my...
方法二:使用切片 除了使用临时变量,还可以利用Python中的切片(Slice)操作来实现列表元素位置的交换。切片操作可以快速地获取列表的子集,从而实现元素位置的交换。 示例代码 # 定义一个列表my_list=[1,2,3,4,5]# 交换第2个和第4个元素的位置my_list[1],my_list[3]=my_list[3],my_list[1]print(my_list...
In this final example, we will use thetranspose() functionfrom Python’sNumPy libraryto transpose the 2D list. First, though, we need to install and import NumPy. Therefore, run the lines of code below to install and import NumPy:
24: Swap Nodes in Pairs https://oj.leetcode.com/problems/swap-nodes-in-pairs/ Given a linked list, swap every two adjacent nodes and return its head. For example, Given 1->2->3->4, you should return the list as 2->1->4->3. Your algorithm should use only constant space. You ...
要修复swapBack函数以获得所需的结果,首先需要了解该函数的功能和预期结果。然后,可以通过以下步骤来修复函数: 1. 检查函数的输入参数和输出结果,确保它们与预期一致。 2. 检查函数内部的逻辑...

每天一算:Swap Nodes in Pairs LeetCode上第24号问题:Swap Nodes in Pairs 题目 给定一个链表,两两交换其中相邻的节点,并返回交换后的链表。示例:给定 1->2->3->4, 你应该返回 2->1->4->3.说明: 你的算法只能使用常数的额外空间。 你不能只是单纯的改变节点内部的值,而是需要实际的进行节点交换。
