Deques

Definition

Deques, short for double-ended queues, are data structures that allow insertion and removal of elements from both ends. They can be used to implement stacks and queues efficiently.

Related terms

Stacks: A stack is a data structure that follows the Last-In-First-Out (LIFO) principle, where elements are added and removed from only one end.

Queues: A queue is a data structure that follows the First-In-First-Out (FIFO) principle, where elements are added at one end and removed from the other end.

Arrays:

Arrays are fixed-size collections of elements stored in contiguous memory locations. They provide fast access to individual elements but have limited flexibility for insertion and deletion operations.
