The column is used to write the basic code definitions and algorithm problems of each data structure, which is convenient for sorting out ideas. The algorithm questions in this article are mainly encountered during personal learning. Because some of them correspond in LeetCode, the question number is attached for reference & only for pers ...

First, you need to understand what is Event Loop? Event Loop is an operating mechanism of computer system. JavaScript uses this mechanism to solve some problems caused by single thread operation. 1. Why is JavaScript single threaded? The single thread of JavaScript is related to its purpose. As a browser scripting language, JavaScript is ma ...

Blocking queue, as the name suggests, is a queue first, and the role of blocking queue in data structure is: Thread 1 adds elements to the queue, and thread 2 takes elements from the queue. When the blocking queue is empty, the operation of fetching elements from the queue will be blocked. When the blocking queue is full, adding elements to th ...

queue Queue is a sequential list, which can be implemented by array (sequential storage) or linked list (linked storage).Follow the principle of first in, first out. That is, the data stored in the queue should be taken out first. After the deposit, it shall be taken out. Simulating queues using arrays The queue itself has a seque ...

Computer experiment of data structure (Chapter III) I 1. Input n (input by the user) numbers within 10, insert them into queue i every time i(0 ≤ i ≤ 9) is input, and finally connect the non empty queues in 10 queues into a chain in the order of queue number from small to large, and output all elements of the chain. Algorithm idea: e ...

Soul torture: why learn data structures? Data structure, to understand it bluntly, is to study the storage mode of data. Data storage has only one purpose, that is, to facilitate the reuse of data in the later stage. Therefore, the storage of data in computer storage space is by no means random, which requires us to choose a good way to store d ...

Advantages of thread pool The work done by the thread pool is mainly to control the number of running threads, put tasks into the queue during processing, and then start these tasks after threads are created. If the number of threads exceeds the maximum number, the exceeded threads queue up, wait for other threads to complete execution, and ...
