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 ...

Your videos are excellent source for new learners ! For this iterative Preorder traversal its using Stack DS. I see in some cases where Queue DS is used in Binary Tree traversal. I couldn't figure out when Stack is to be used and when Queue is to be used in Binary Tree. Do you have any video which is using Queue/Dqueue DS instead of Stack DS ? I want to understand the implementation using Queue/Dqueue DS. Thanks again for your excellent videos !

Its there !!! In bfs we use queue and in dfs we use stack

Can you please tell me, Which one is recommended to use? Recursive Version OR Iterator Version? Please give Replay to me, Thank you
@itsdineshvaryani 4 жыл бұрын
Recursion has simple code while performing tree traversals ... Both has same time and space complexities ... But its preferred to use iterative ... Bcoz it avoids stack to get overflow ...

if you understand the way stacks work, the way he explains it is clear enough. The root node is passed into the stack, but with the LIFO principle, the procedure shows how they are processed (iteratively)

Would doing this with a queue instead give you post-order traversal?
