Data Structures and Algorithms is an important aspect of every coding interview. This Algorithms and Data Structures course will teach you everything you need to prepare for placements, coding interviews, and logic building. This playlist will teach you how to create optimal solutions to real-world problems. This course will cover a wide variety of data structures and algorithms. Want to land a software engineering job in the IT industry? This course - 'Data Structures and Algorithms' is here to help. The course walks you through multiple Java algorithms, data structure problems, and their solutions with step-by-step visualizations, so that you are actually learning instead of blindly memorizing solutions. The course covers in and outs of Data Structures and Algorithms in Java. Java is used as the programming language in the course. Students familiar with Javascript, Python, C#, C++, C, etc will also get to learn concepts without any difficulty. The implementation of various Algorithms and Data Structures have been demonstrated and implemented through animated slides. It covers many interview room questions on Algorithms and Data Structures. The course covers topics such as - 0. Algorithm Analysis 1. Arrays 2. Matrix 3. Singly Linked List 4. Doubly Linked List 5. Circular Singly Linked List 6. Stacks 7. Queues 8. Binary Tree 9. Binary Search Tree 10. Graphs 11. Priority Queues and Heaps 12. Recursion 13. Searching 14. Sorting 15. Strings 16. Trie Data Structure 17.
