Study Notes
Data Structures & Algorithms (DSA) Introduction
- The course covers data structures and algorithms.
- Prerequisites include C++ basics (variables, functions, pointers), object-oriented programming (OOP) in C++ (classes, objects, templates, friend functions), and asymptotic notation (Big-O).
- The course grading includes a midterm (15%), practical projects and practical assignments (15%), and an oral exam (10%).
Pre-requisites
- Basics of C++: Covers fundamental programming concepts in C++.
- OOP using C++: Covers object-oriented programming concepts utilizing the C++ language.
- Asymptotic Notations: Introduces Big O notation, which is crucial for evaluating algorithmic efficiency.
Course Timeline
- Week 1: Introduction to data structures and algorithms.
- Week 2: Static Arrays
- Week 3: Dynamic Arrays
- Week 4: Linked Lists
- Week 5: Stacks
- Week 6: Queues
- Week 7: Trees
- Week 8: Binary Search Trees
- Week 9: Hash Tables
- Week 10: Heaps
- Week 11: Graphs
- Week 12: Strings
Rules
- The presentation had icons for time, phone, chat bubbles, and people, suggesting rules for the class. Specific details of these rules were not listed.
Objective
- The objective is to understand fundamental data structure concepts and their importance in algorithm analysis and programming.
Before Proceeding
- Problem
- Algorithm
- Program
Algorithm, Program, Data Structure
- Before programming, understand the problem's solution approach.
- Prioritize the program's behavior over specific implementation methods.
- Focus on the operations of the program (modifying, searching, storing).
- The implementation should choose the data structure to optimize time and space complexity.
- The best data structure balances storage and computational efficiency.
Why Study Data Structures?
- Understanding data structures improves problem-solving and programming skills.
- Efficient software/applications depend on proper data structuring.
- Mastering data structures provides a well-defined toolbox for solving complex problems.
- Strong data structure knowledge can enhance career prospects.
Data Structures and Visualisation
- Data structures help efficiently manage and utilize data.
- The presentation used the example of a library, where organized books are easier to find than disorganized ones.
Data Structure Types
- Primitive Data Structures: Basic data types like integers, floats, characters, and booleans.
- Non-Primitive Data Structures: Advanced data types.
- Linear: Arranged sequentially (arrays, linked lists, stacks, queues).
- Non-Linear: Hierarchical or unstructured arrangement (trees, graphs, heaps, sets, tries, hash tables).
- Homogeneous: All elements have same data type (arrays).
- Non-Homogeneous: Elements can have different data types (structs).
- Static Data Structures: Fixed size (arrays). Contents modifiable but no change to allocated memory space.
- Dynamic Data Structures: Size can change during operations. Allocate memory space on the fly.
ADT
- Abstract Data Type (ADT): A data type defined by operations without specifying implementation details.
- Data Structure: The physical implementation of an ADT.
Stack ADT
- Stack: Elements stored in sequential order with operations happening at the top.
- Operations include push (insert), pop (remove and return), peek (return top element), size (count elements), isEmpty (check if empty), isFull (check if full).
Choosing the Right Data Structure
- Analyze the data type (structured/unstructured, order, duplication, relationships).
- Identify required operations (searching, insertion, deletion, etc.).
- Evaluate the time and space complexity of the data structure.
- Consider scalability.
- Check if built-in libraries are suitable for common use cases.
- Thoroughly test under realistic conditions and benchmark.
