  • Four common data structures in standard library collections


    Collections library is a part of the standard library. There are many data structures in it. Many modifications and improvements have been made on the basis of lists, dictionaries and tuples. Today, let’s talk about the most useful ones. 1、deque It implements a queue that can be operated at both ends, which is equivalent to […]

  • Rnaflow a new fully automatic RNA_ Seq data analysis process


    Recently, I picked up a job to help other teachers in the college analyze the rice transcriptome, but my daughter-in-law rushed to graduate and wanted to help her with articles and data. She didn’t have time to do this. Although she can analyze the transcriptome, she hasn’t realized automation, so I wandered around in Google […]

  • Reading redis source code — adlist (10)


    Double ended linked list adlist.c .h The list in redis is in the form of a double ended linked list typedef struct listNode { //Front node struct listNode *prev; //Post node struct listNode *next; //The value of the node void *value; } listNode; /* *Double ended linked list structure */ typedef struct list { //Header […]

  • 016 learn the safe double linked list layout of rust through the linked list


    introduce Video address:www.bilibili.com/video/av78062009/Relevant source code:github.com/anonymousGiga/Rust-link… Details At the beginning of this section, we will design a secure double ended queue. For the layout of double ended queues, we mainly use RC and refcell. Rc RC: data can be shared through the RC pointer. Because the rust language has the concept of ownership, after the data […]

  • 025 realize double ended queue by using stack of linked list rust


    introduce Video address:www.bilibili.com/video/av78062009/Relevant source code:github.com/anonymousGiga/Rust-link… Details In this section, we use stack to implement double ended queue. Implementation stack The implementation of stack is basically similar to the implementation of single linked list at the beginning, as follows: pub struct Stack<T> { head: Link<T>, } type Link<T> = Option<Box<Node<T>>>; struct Node<T> { elem: T, next: […]

  • This article takes you to understand the queue data structure


    Abstract:For the queue, the data structure is more complex than the stack, but it is not very difficult to understand the first in first out, and then implement it with array or linked list. This article is shared from Huawei cloud community《Handwritten all kinds of queue, a text is done》Author: bigsai. preface Stack and queue […]

  • Maximum value of sliding window


    239. Sliding window maximum Solution 1: monotone queue + binary search thinking The elements in a monotonic queue are incremental. Every time you slide the window, the current element is inserted into the queue by dichotomy, and the first element of the window is deleted from the queue. At this time, dichotomy is also used. […]
