What are the various types of data structures?

The main types of data structures are commonly divided into two categories: Primitive and Non-Primitive. Primitive data structures include basic types like integers (int), floating-point numbers (float), characters (char), and booleans (bool). Non-Primitive data structures are more complex and include arrays, lists, stacks, queues, trees, graphs, and hash tables.

How do stacks and queues differ in terms of data handling?

Stacks and queues are both linear data structures but differ in how elements are removed. A stack operates on a Last In, First Out (LIFO) principle, meaning the last element added is the first to be removed, suitable for scenarios like undo mechanisms in software. A queue operates on a First In, First Out (FIFO) principle, making it ideal for situations like processing requests on a server where requests should be handled in the order they arrive.

What is a linked list, and how is it different from an array?

A linked list is a dynamic data structure consisting of nodes, where each node contains data and a reference (or link) to the next node in the sequence. Unlike arrays, linked lists do not store data in contiguous memory locations, making them more flexible for adding or removing elements without reallocating the entire structure. This flexibility comes at the cost of slower access times to individual elements compared to arrays.

What are the advantages of using a graph data structure?

Graphs are powerful data structures used to represent complex relationships between elements, such as networks. The advantages include the ability to model real-world problems like social connections, transportation networks, and internet routing. Graphs are versatile, supporting both directed and undirected relationships, and can include additional information such as weight or capacity on connections.

What are trees used for in data structures?

Trees are non-linear data structure types used to represent hierarchical data. They are used extensively for organizing data in a structured manner, allowing quick search, insert, and delete operations. Common applications of trees include database indexing with binary search trees, storing hierarchical relationships such as a file system, and decision-making processes in machine learning algorithms using decision trees.

What are data types in data structures?

Data types in data structures mean the categorization of data to inform the programming language how the programmer intends to use the data. Basic data types include integers, floats, characters, and booleans, which are directly supported by the language at a low level. Data structures use these data types to define and organize data in a meaningful way, such as numerical arrays or character strings.

What are the types of data structures in C?

C language supports several types of data structures, mainly categorized into primitive and composite types. Primitive types include int, char, float, and double. Composite types, which are user-defined, include arrays, structs, unions, linked lists, stacks, queues, trees, and graphs. These help in building more complex data structures suited to various programming needs.

What are the different types of tree data structures?

Trees come in various forms, each optimized for specific uses:Binary TreeBinary Search Tree (BST)AVL TreeRed-Black TreeSegment TreeTrie (Prefix Tree)

What are the types of queue data structures?
