About this ebook
The book begins with essential programming concepts and gradually introduces important data structures such as arrays, linked lists, stacks, queues, trees, heaps, graphs, hash tables, and tries. It also covers fundamental and advanced algorithms, including searching, sorting, recursion, backtracking, greedy algorithms, divide and conquer, dynamic programming, and graph algorithms.
Each topic is explained using clear concepts, practical examples, step-by-step logic, algorithms, and programming implementations in both C and Java. The book also focuses on time and space complexity, helping readers understand how to analyse and optimise program performance.
Key topics include:
• C and Java programming fundamentals
• Algorithm analysis and Big-O notation
• Arrays and strings
• Linked lists
• Stacks and queues
• Recursion and backtracking
• Searching and sorting algorithms
• Trees and binary search trees
• Heaps and priority queues
• Hashing and hash tables
• Graphs and graph traversal
• Greedy algorithms
• Divide and conquer
• Dynamic programming
• Advanced data structures and algorithms
• Problem-solving and competitive programming techniques
By learning the same DSA concepts through both C and Java, readers can understand the underlying logic of data structures while also developing modern object-oriented programming skills. This book is suitable for B.Tech, BCA, MCA, computer science students, programmers, interview candidates, and competitive programming learners.
Whether you are preparing for technical interviews, coding assessments, university examinations, or software development careers, this book provides the knowledge and practical skills required to solve programming problems efficiently and confidently.
