Note: Mr. Liu's notes on the content of algorithm design and analysis course this semester People who have to stick to it until the end feel great Besides, PPT is not well understood by the teacher behind the teacher. Of course, it may be because I am always distracted and make complaints about it. 🤔 Branch gauge Loading problem analysis 🚩 ...

Research on the principle of concurrent linkedqueueintroduceConcurrentLinkedQueue is a thread safe unbounded non blocking queue. The bottom layer uses one-way linked list to achieve thread safety. CAS is used for incoming and outgoing operations.The internal queue of ConcurrentLinkedQueue is implemented in the way of one-way linked list, in whi ...

Blocking queue LinkedBlockingQueueintroduceThe previous article introduces the non blocking queue concurrent linkedqueue implemented by CAS algorithm, and this article introduces the blocking queue LinkedBlockingQueue implemented by exclusive lock.The class diagram shows that the LinkedBlockingQueue is also implemented using a one-way linked li ...

Title Description Given an array num and the size k of the sliding window, please find the maximum value in all sliding windows. Example: Input: nums = [1,3,-1,-3,5,3,6,7], and k = 3 Output: [3,3,5,5,6,7] Explanation: Position {maximum value of sliding window ---------------               ----- [1  3  -1] -3  5  3  6  7       3  1 [3  -1  - ...

1. What is the priority queue??First, the priority queue is a queue. It also has all the properties of the queue.Secondly, the priority queue takes out the element with the highest priority every time.The interior of the priority queue is maintained by heap. Put the highest priority first.2. When will this queue be used??After reading the defin ...

The k-th largest element of the array Title Link There are two ways to use the heap: Use the small root heap with the size of the total number of elements. After k elements are popped, the top element of the heap is the k-largest element among all elements.Maintain a K-size large root heap, so that the first k largest elements of all e ...

7-1 symmetrical sorting (25 points) The title comes from PTA You work for the albatross circus with a group of ugly stars as pillars. You have just completed a program that outputs their list in non descending order according to the length of the stars' name string (that is, the length of the current name is at least the same as that of th ...

summary Baidu Encyclopedia: Queue is a special linear table, which only allows deletion at the front of the table and insertion at the back of the table. Like stack, queue is a linear table with limited operation. The end that performs the insertion operation is called the tail of the queue, and the end that performs the deletion operation ...
