In this comprehensive guide Prateek Narang (Software Engineer & Educator, SCALER) will help you dive into the fundamental concepts of Hashtables and HashMaps. Checkout the FREE masterclasses by industry experts here: https://www.scaler.com/events/?utm_so... This in-depth exploration will help you understand and harness the power of these fundamental data structures. In this video, we delve into the inner workings of Hashtables and Hashmaps, we will understand all the concepts of searching, insertion, deletion, rehashing and much more. What is HashMaps? HashMaps are data structures that store and retrieve data using key-value pairs, providing efficient lookup, insertion, and deletion operations based on hashing. What is Hashtables? Hashtables, also known as hash maps, are data structures that use hashing to store and retrieve data quickly. They provide constant-time average-case complexity for operations such as search, insert, and delete. What is Rehashing? Rehashing is the process of resizing a hash table to accommodate more elements. It involves creating a new, larger array, recalculating the hash codes of existing elements, and redistributing them into the new array to maintain optimal load factor and performance. What is DSA? DSA stands for Data Structures and Algorithms. It refers to a set of techniques and methods used to organise and manipulate data in a computer program. Data structures are a way of organising and storing data in a way that enables efficient access and modification, while algorithms are a set of instructions that perform a specific task or solve a problem. What is data structure? A data structure is a way of organising and storing data in a computer program so that it can be accessed and manipulated efficiently. It defines a set of rules for how data is organised, how it is accessed, and how operations can be performed on it. Examples include arrays, linked lists, and trees. What is an algorithm? An algorithm is a set of instructions for solving a problem or performing a task in a computer program. It defines a series of steps or procedures that must be followed in order to achieve a desired outcome. Algorithms are used in a wide range of applications, from search engines to robotics. Types of DSA There are many types of Data Structures and Algorithms (DSA) including arrays, linked lists, stacks, queues, trees, graphs, hash tables, and sorting and searching algorithms. Each DSA has its own strengths and weaknesses and is suitable for different types of data processing and storage needs. Applications of DS Data Structures have a wide range of applications in computer science, including database management, algorithm design and analysis, operating systems, artificial intelligence, machine learning, and web development. They are used to store, organise, and manipulate large amounts of data efficiently and effectively, enabling faster and more accurate processing of information.
