Summary of Python Advanced 2 - Abstract Data Types - Stack, Queue, Linked List and Binary Tree
The video focuses on abstract data types in Python, covering Stacks, Queues, Linked Lists, and Binary Trees. The implementation of these data types using Python is discussed, along with the methodology for each. The video emphasizes taking breaks and suggests tackling one data type at a time to avoid overwhelm. The speaker provides detailed explanations and examples of each data type, including how to code a linked list and a binary tree. The methodology presented in the video includes:
- Practice coding a linked list in Python without creating anything new
- Understanding the structure of a binary tree with left and right children
- Implementing a binary tree using classes and nodes
- Adding values to a binary tree based on comparisons
- Explaining the concept of traversing a binary tree in in-order, pre-order, and post-order
- Using recursion for coding traversal algorithms
- Demonstrating adding nodes to a binary tree
- Highlighting the importance of practice for mastering these concepts
### Methodology:
- Understand object-oriented programming concepts.
- Utilize 1D and 2D arrays.
- Define abstract data types with both data and operations.
- Implement Stacks using arrays and a stack pointer.
- Implement push operation in a Stack.
- Implement pop operation in a Stack.
- Initialize and test a Stack program.
- Implement Queues using two pointers.
- Define linear queue data structure and operations.
- Initialize and test a Queues program.
- Implement Linked Lists using arrays and/or classes.
- Define ordered and unordered Linked Lists.
- Create a Linked List using a node class.
- Define and test an unordered Linked List program.
- Define a circular queue and its operations.
- Implement insertion and deletion in Linked Lists.
- Implement search and output operations in Linked Lists.
- Implement ordered insertion in Linked Lists.

— « if root 0 is not -1, then call the in order function again and again until you reach -1, so you do left, root, right. This is in order.
