Using interface-oriented programming in Java, which is for abstract programming, is a better way to reduce coupling ArrayList LinkedList is a sub-class of list, like Set is also collection sub-interface its implementation has HashSet LINKEDH Ashset TreeSet, etc. Many times in the work, we need to put many kinds of instance objects, all thrown into a set, this time we should find a standard, interface is a standard. Or it can be understood that many k

Title Link: https://leetcode.com/problems/rotate-list//* Test instructions: Give a list, rotate the list to the right K position *//** * idea: the right-hand k position, quite with the list from the len-k position truncated, and then * the two linked list exchange position,

A tag is actually used to make a jump.The role of a tag: page jump, anchor (page is a bookmark-like thing, in the URL to show #)Traget = "_blank" This property means that after clicking on the new window opens the connection, if no change is meant to be opened directly on this page.href=# Plus Tag numberIMG TagsIf clicking on the image requires a hyper-connected jump function, the implementation is as follows:Property:SrcTitleAltStyleUL Label: A point is shown in front of the

The complete code for implementation is as follows: Delete the reciprocal k node in a single linked list and double linked list public class deletelist{//single linked list node definition public static class node{int value; Node Next; public Node (int data) {this.value=data; }///delete the reciprocal K node in the single linked

A series of questions about linked lists are described earlier, and here we introduce a more representative algorithm for the reversal of unidirectional lists. In the reversal of the time must remember the multi-drawing, more to understand when the list is reversed when it changes the address, this and the array of data is very inconsistent.　　 Publicnode reverselist (node head) {//determine if a linked list

Tags: linux linked listDelete a node from the linked list using the list_del interface. Pay attention when using list_del.The list_del implementation is as follows:Static inline void list_del (struct list_head * entry){_ List_del (entry-> prev, entry-> next );Entry-> next = list_python1;Entry-> prev = list_python2;}Static inline void _ list_del (struct list_head * prev, struct list_head * next){Next-> prev = prev;Prev-> next = next;}In fact, it is to

Sort list Sort a linked list inO(NLogN) Time using constant space complexity. Note: Merge Sorting: time O (nlogn) and space O (1). the linked list is split into two parts each time and then merged. Fast sorting (using two pointers) /** * Definition for singly-linked list. * struct ListNode { * int val; * Li

Starting from the first node of M to the nth node, insert the already traversed node after the M-1 node and ensure that the next * of the M node points to the next of the traversal node to avoid a broken list
