Introduction to Data Structures

• Foundational Data Structures:

  • Arrays
  • Linked Lists
  • Hash Tables
  • Stacks
  • Queues
  • Graphs
  • Trees

• CRUD Operations: Create, Read, Update, Delete data efficiently.

Explanation and Analogies

• Array: Like a row of numbered cubbies.
• Linked List: A treasure map of clues.
• Hash Table: A locker with specific names.
• Stack: A stack of books.
• Queue: A line of kids at the cafeteria.
• Graph: Resembles a spider web.
• Tree: Like a literal tree.

Advanced Data Structures and Concepts

• Binary Search Tree: Improves algorithm time complexity from O(n²) to O(log n).

• B-Tree:

  • Developed to address scalability issues of binary search trees.
  • Self-balancing, allows nodes to have multiple children.
  • Efficient for modern data systems like databases and file systems.

• Radix Tree:

  • Efficient for storing and searching data with shared prefixes, e.g., IP addresses.
  • Merges nodes with only one child for efficiency.

• Rope:

  • Efficient for modifying large strings in text editors.
  • Breaks down strings into manageable chunks.

• Bloom Filter:

  • A probabilistic data structure for fast membership tests.
  • Results in no false negatives with potential false positives.

• Cuckoo Hashing:

  • Inspired by the cuckoo bird's behavior.
  • Collision resolution technique maintaining constant time for lookups.

Code Optimization Tool

• Code Rabbit Extension:
  • Advanced code reviews and bug detection in VS Code.
  • Offers line-by-line comments and one-click fixes.
  • Free to use and compatible with various forks of VS Code.
