preface: Hello, everyone. Today is the eighth day of LeetCode's daily question. What I share is the reversal of the linked list and the difficulty coefficient of two stars! No more nonsense, let's start with the topic! 1.1 subject requirements Topic type: linked list inversion Title Content: reverse the link order of the single linked ...

1, Linear table A linear table is a finite sequence of n data elements with the same characteristics. Common linear tables are: Sequential list, linked list, stack, queue, string The logic of a linear table is a linear structure, that is, a continuous line. However, the physical structure is not necessarily continuous. When a linea ...

Data structure and algorithm learning notes (C language) Circular linked list 1. Definition: circular linked list is another form of linked storage structure. Its feature is that the pointer field of the last node in the table points to the head node, and the whole linked list forms a ring. If the circular linked list is an empty list, the ne ...

Binary sort tree Binary sort tree properties: If its left subtree is not empty, the values of all nodes on the left subtree are less than the values of its root nodeIf its left subtree is not empty, the values of all nodes on the left subtree are less than the values of its root nodeIts left and right subtrees are also binary sort trees The ...

SET key2 value2 OK MGET key1 key2 key3 # returns a list "value1""value2"(nil) MSET key1 value1 key2 value2 MGET key1 key2 "value1""value2" #### ⑤ , expiration, and SET command extensions Yes key Set the expiration time, and the expiration time will be automatically deleted. This function is often used to control the expiration time ...

Basic knowledge of linked list LRU cache elimination algorithm A classic application scenario of linked list is LRU cache elimination algorithm. LRU least recently unused algorithm. The algorithm is used in the OS virtual memory part. According to the locality principle of the program, the virtual memory is designed. Only a few memory ...

Chapter 2 linked list (2) This article is used to record the code involved in the review of data structure, the problems encountered and the solutions Wang Tao after class exercises 2.2 delete all nodes with the value of X and free up their space; The node with value x is not unique void Del_x(LinkList &L, int x){ LNode *q = L ...

1 recursively reverse the entire linked list For recursive algorithms, the most important thing is to clarify the definition of recursive functions. Specifically, our reverse function is defined as follows: Enter a node head，take「with head As the starting point」The linked list of is inverted and returns the head node after inversion. Und ...

1. Introduction to linked list structure We have learned the use of arrays in the previous chapters. The space of arrays is continuous and the size of arrays is constant. In many application scenarios of dynamic data storage, it is inconvenient to use; The linked list structure introduced in this article supports the dynamic addition and relea ...

In the interview, I often ask about JUC. The common one is CHM. Let's talk about the methods and operations of different versions of CHM The underlying implementation of CHM in JDK7 is implemented by segmented segment array. Segment contains hashentries, and each HashEntry forms a linked list. Common get methods: First, obtain the lock of se ...
