What is a list?

A list is a collection of items that are stored and accessed sequentially. Each item in a list is identified by an index number, starting from 0 for the first item in the list. Lists can contain elements of any data type, including integers, strings, and objects. They can also be modified by adding, removing, or changing elements. Lists are often used in programming for various purposes such as organizing data, sorting, and processing information. Some programming languages provide built-in functions for performing various operations on lists, such as sorting, filtering, and merging lists. There are also different types of lists such as linked lists, dynamic arrays, and circular lists.
