Study Notes

Tree Traversals

In-order sequence and post-order sequence are types of tree traversals
Pre-order traversal, in-order traversal, post-order traversal, and breadth-order traversal are different types of tree traversals
Algorithms based on tree traversals include calculating the height of a binary tree, counting the number of nodes in a tree, and searching for a value in the tree

Binary Search Trees

A binary search tree (BST) is a type of tree that has a specific structure
Basic operations in a BST include checking if a value is in the BST, adding a value to the BST, and removing a value from the BST
The importance of BSTs lies in their efficiency and ability to perform operations quickly

The Table ADT

The Table ADT is a data structure that stores and retrieves data
The Table ADT implementation involves using arrays and hash tables
The efficiency of the Table ADT implementation depends on the specific implementation

Object Oriented Programming

Mutable vs Immutable objects are two different types of objects
Inheritance is a concept in OOP that allows classes to share common properties
Overriding a method is a way to provide a specific implementation of a method in a subclass
Summary of OOP concepts includes understanding mutable vs immutable, inheritance, and overriding

Three Kinds of Tasks

There are three kinds of tasks: example problems, subset sum, and operation: peek()
Example problems include adapting Python lists to implement stacks and queues

Node ADT

The Node ADT is a data structure that represents a single node in a linked list
Node chains are a series of nodes connected together
Nodes are used to implement stacks and queues

Defensive Programming

Defensive programming is a practice that involves anticipating and mitigating potential errors
It involves understanding what could go wrong and taking steps to prevent it
Defensive programming is important for writing robust and reliable code

Node-based Stacks and Queues

Node-based stacks and queues are data structures that use nodes to implement stacks and queues
Using nodes to implement stacks and queues provides flexibility and efficiency
Node-based stacks and queues are used in applications such as buffering communications and backtracking

Objects and Classes

Objects and classes are fundamental concepts in object-oriented programming
Classes define the structure and behavior of objects
Objects are instances of classes and can have their own attributes and methods

Stacks and Queues

Stacks and queues are data structures that follow a specific order of operations
Stacks are Last-In First-Out (LIFO) while queues are First-In First-Out (FIFO)
Applications of stacks and queues include buffering communications, backtracking, and evaluating postfix expressions

Applications of Stacks and Queues

Queueing simulation is an application of stacks and queues
Bracket checking is another application of stacks and queues
Post-fix arithmetic evaluators use stacks and queues to evaluate expressions

List-based Stacks and Queues

List-based stacks and queues are data structures that use lists to implement stacks and queues
Adapting Python lists to implement stacks and queues involves using specific operations such as size(), is_empty(), push(), pop(), and peek()
List-based stacks and queues are used in applications such as buffering communications and evaluating postfix expressions
