  • Four common data structures in standard library collections

    Time:2022-3-13

    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

    Time:2022-1-11

    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 […]

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

    Time:2021-8-6

    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

    Time:2021-7-27

    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: […]

    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. […]
