What is the difference between ArrayList and rule list? Rule List1. General differences between ArrayList and rule list(1). ArrayList is a dynamic array-based data structure. The ArrayList is based on the linked list data structure.ArrayList: elementData [size] storage. The value increases dynamically by 50%, which may cause a waste of memory.Worker
Content SummaryThis chapter focuses on a practical example of using a recursive manipulation list: Determining whether an element is contained in a list.It's time to introduce the example of a program in the first Prolog that uses a recursive manipulation list. One of the things that interests us most is whether an object is an element in a list. So, we want to w

I. Overview
List stores elements in the linked list in sequence. Compared with vectors, list allows fast insertion and deletion, but random access is slow.
A list is not only a two-way linked list, but also a ring two-way linked list

List data types and common operations of python, and list data types of python
A list is the most common Python data type. It can appear as a comma-separated value in square brackets.
Each element in the list is assigned a number-its location, or index. The first index is 0, the second index is 1, and so on.
Operations
Question: In a sorted list, how to delete duplicate nodes. For example, the following figure:
The detailed implementation code is as follows:
Delete duplicate node void deleteduplication (listnode** phead) {if (Phead = = NULL | | *phead = NULL) return;
listnode* Pprenode = NULL;
listnode* pnode = *phead;
while (Pnode!= NULL) {ListNode *pnext = pnode->m_pnext;
BOOL Needdelete = false;
if (pnext!= NULL pnext->m_nvalue
