Study Notes

Abstract Data Types (ADTs)

Defined as classes or types for objects, characterized by a set of values and operations associated with them.
Fundamental concepts include spaghetti code, modular code, structured programming, and object-oriented programming.

Types of Abstract Data Types

LIST ADT: Organizes elements of the same type in sequential order.
- get(): Returns an element from a specific position.
- insert(): Inserts an element at any position in the list.
- remove(): Removes the first occurrence of a specific element.
- removeAt(): Removes an element from a specified location.
- replace(): Substitutes an element at a certain position with another.
- size(): Returns the total number of elements in the list.
- isEmpty(): Checks if the list is empty; returns true if so.
STACK ADT: Contains elements of the same type, also arranged sequentially, with operations limited to one end, known as the top.
- push(): Inserts an element at the top of the stack.
- pop(): Removes and returns the element at the top if not empty.
- peek(): Returns the top element without removing it.
- size(): Provides the count of elements in the stack.
- isEmpty(): Validates if the stack is empty; returns true if it is.
- isFull(): Checks if the stack is full; returns true if so.
QUEUE ADT: A structure where elements are arranged in sequential order, with operations taking place at both ends (FIFO - First In, First Out).
- enqueue(): Inserts an element at the end of the queue.

Description

This quiz focuses on Abstract Data Types (ADTs), including their definitions and examples such as List ADT, Stack ADT, and Queue ADT. It also addresses programming concepts related to ADTs like spaghetti code, modular code, structured programming, and object-oriented programming.
