What is a Data Structure?
A data structure is a storage format that defines the way data is stored, organized, and manipulated. Some popular data structures are Arrays, Trees, and Graphs.
What is an Array?
An array is commonly referred to as a collection of items stored at contiguous memory locations. Items stored are of the same type. It organizes data so that a related set of values can be easily sorted or searched.
What is a Stack?
A stack refers to a linear data structure performing operations in a LIFO (Last In First Out) order. In a stack, elements can only be accessed, starting from the topmost to the bottom element.
What are Binary Trees?
A binary tree is an extension of the linked list structure where each node has at most two children. A binary tree has two nodes at all times, a left node and a right node.
