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.
Deque Data Structure
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 end
Applications 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.

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.

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.
