Familiarize yourself with common operations such as insertion, deletion, and traversal.熟悉插入、删除、遍历等常用操作。 Practice reversing a linked list, finding the middle element, and detecting cycles.练习反转链表、查找中间元素以及检测循环。 3. Use Multiple Pointers 3. 使用多个指针 Many linked list...
题目:Sort a linked list using insertion sort. 即使用插入排序对链表进行排序。 思路分析: 插入排序思想见《排序(一):直接插入排序 》 C++参考代码: /** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next; * ListNode(int x) : val(x), next(NULL) {} ...
If there are multiple suitable places for insertion, you may choose any place to insert the new value. After the insertion, the circular list should remain sorted. If the list is empty (i.e., given node isnull), you should create a new single circular list and return the reference to ...
Implement these functions in your linked list class: get(index) : Get the value of theindex-th node in the linked list. If the index is invalid, return-1. addAtHead(val) : Add a node of valuevalbefore the first element of the linked list. After the insertion, the new node will be...

Insertion Sort List Medium java 148 Sort List Medium java 小结 链表的问题是面试当中常常会问到的,比如链表的倒置,删除链表中某个结点,合并两个排序链表,合并 k 个排序链表,排序两个无序链表等。 这些题目一般有一些相应的技巧可以解决。 第一,引入哨兵结点。如我们开头说的 dummy node 结点。在任何时候,不管...
