我的github连接:https://github.com/princewen/leetcode_python 21. Merge Two Sorted Lists Merge Two Sorted Lists 很简单的链表拼接题,但是要注意两个地方 1、返回值要返回head.next 2、无需判断循环后哪个不为空,or返回第一个为真的值 # Definition for s

LeetCode with Python -> Linked List 21. Merge Two Sorted Lists Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. Example: Input:1->2->4, 1->3->4Output:1->1->2->3->4->4 1 2 3 ...
Linked List Cycle 链表循环Description: Detect if a cycle exists in a linked list.描述:检测链表中是否存在环。Hint: Use two pointers (slow and fast); if they meet, a cycle exists.提示:使用两个指针(慢速和快速);如果它们相遇,则存在循环。Solution: see here 解决办法:看这里 Merge Two Sorted Li...
Given a sorted linked list, delete all duplicates such that each element appear onlyonce. Example 1: Input: 1->1->2 Output: 1->2 Example 2: Input: 1->1->2->3->3 Output: 1->2->3 COde #Definition for singly-linked list.#class ListNode:#def __init__(self, val=0, next=None...
Given a sorted linked list, delete all duplicates such that each element appear only once. For example, Given 1->1->2, return 1->2. Given 1->1->2->3->3, return 1->2->3. 题意:对给定的排好序的链表,删除重复的元素,只留下出现一次的元素 ...
Python has lists, obviously, but they're really arrays under the hood. I decided to try my hand at creating a proper linked list class, one with the traditional advantages of linked lists, such as fast insertion or removal operations. I'm sure I was reinventing the wheel, but this was ...
6. Carry on in this manner until the full list has been sorted. 5. display() function displays every node present in the list: 1. Create a fresh node called 'current' that points to the head. 2. Print current→data until it reaches null. ...
