What is an Array ? | DSA in one minute

An array is a data structure that stores a collection of elements of the same data type. It is used to store and access a large number of items efficiently. An array is a linear data structure, meaning that the elements are stored in a sequential manner and can be accessed one by one.

In computer programming, an array is often used to store a list of items, such as a list of names or a list of numbers. Each element in the array is assigned a numerical index, which can be used to access and manipulate the element. Arrays can be one-dimensional, meaning that they have a single row or column of elements, or they can be multi-dimensional, with multiple rows and columns.

In many programming languages, arrays are implemented using a combination of memory locations and pointers, allowing for fast and efficient access to the elements in the array. They are a fundamental data structure that is commonly used in a wide range of applications.
