Deque meaning in DSA Last Updated : 23 Jul, 2025 Comments Improve Suggest changes Like Article Like Report Deque, which stands for Double Ended Queue, is a special type of queue that allows adding and removing elements from both front and rear ends. Characteristics: of Deque:Dynamic size: The size of a deque can change dynamically during the execution of a program.Linear: Elements in a deque are stored linearly and can be accessed in a sequential manner.Double Ended: Elements can be added and removed from both the front and the rear endApplications of Deque:Browser History: A deque can be used to store the history of recently visited web pages.Text Editor: A deque can be used to undo and redo operations in a text editor.Disk Scheduling: A deque can be used to schedule disk requests to improve disk performance.To learn more about applications, please refer to this article.Advantages of Deque:Dynamic Size: The size of a deque can be adjusted dynamically during the execution of a program.Versatility: A deque can be used as both a queue and a stack, making it a versatile data structure.To learn more about advantages, refer to this article.Disadvantages of Deque:Complexity: The implementation of a deque is more complex than that of a queue or a stack.Overhead: The overhead of adding or removing elements from both ends of a deque is greater than that of adding or removing elements from only one end.To learn more about the advantages, refer to this article.What else can you read?Introduction to DequeApplications, Advantages and Disadvantages of DequeDifferent Types of Queue Comment More infoAdvertise with us Next Article Graph definition & meaning in DSA N nayan_nand Follow Improve Article Tags : Queue DSA Definitions and Meanings deque Practice Tags : DequeQueue Similar Reads Hashing meaning in DSA Hashing is defined as a data distribution technique that transforms given key into a different value using hash function for faster access to data.

It is a data structure that allows adding and removing elements from both ends efficiently. Unlike regular queues, which are typically operated on using FIFO (First In, First Out) principles, a deque supports both FIFO and LIFO (Last In, First Out) operations.E 6 min read Deque in Python A deque stands for Double-Ended Queue.
