Array

Definition

A data structure consisting of a collection of elements identified by index or key.

Deep Dive

An array is a fundamental data structure in computer science that stores a fixed-size, sequential collection of elements, typically of the same data type. Each element in an array is identified by an index or key, which represents its position within the array, allowing for direct and efficient access to any element. Arrays are often stored in contiguous memory locations, making them highly optimized for operations that require traversing elements or accessing them by their position.
