    Want to land a software engineering job in the IT industry? This course - 'Visualizing Data Structures and Algorithms' is here to help. The course walks you through multiple Java algorithms, data structures 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 questions and solutions are demonstrated by -
    1. Animated slide. (To make visualization of algorithms faster)
    2. Coding algorithm on IDE.
    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. Dynamic Programming
    and many more ...

    i really like the idea of using call stack to visualize the process. That's for the clarification!

    Perfect explanation, I have searched for this topic in many reputed CZcams channels but no one was able to make students understand the code properly. That call stack was the key point for understanding the concept. Understood the working of traversal now, thank you so much.
