Learning Resources

Welcome to the learning resources section. This area contains structured educational content to help developers master fundamental concepts and techniques.

Algorithms

The Algorithms section provides comprehensive guides on common algorithmic patterns used in coding interviews and real-world problem solving. Each algorithm pattern includes:

• Clear explanation of the approach
• When and how to apply the pattern
• Three real LeetCode examples with detailed solutions
• Step-by-step walkthroughs designed for easy understanding

Available Algorithm Patterns

• Core Patterns:

  • Sliding Window - Optimize problems involving contiguous subarrays or substrings
  • Dynamic Programming - Break down complex problems into simpler subproblems
  • Two Pointers - Efficiently process arrays or lists with multiple pointers
  • Fast and Slow Pointers - Detect cycles and find middle elements
  • Backtracking - Explore all possible solutions through systematic search

• Search and Optimization:

  • Binary Search on Answer - Find optimal solutions using binary search
  • Greedy Algorithms - Make locally optimal choices for global optimum

• Data Structures:

  • Heap and Priority Queue - Maintain sorted order for efficient min/max access
  • Monotonic Stack - Find next greater/smaller elements efficiently
  • Trie (Prefix Tree) - Efficient string prefix operations

• Graph Algorithms:

  • Graph Traversal (BFS/DFS) - Explore graphs systematically

Data Structures

Understanding fundamental data structures is essential for implementing efficient algorithms:

• Arrays and Multidimensional Arrays - Master array fundamentals, operations, and common patterns
• Hash Tables and Sets - Fast lookups and membership testing for optimization

Additional Topics

Algorithm Analysis

• Space Complexity Analysis - Understanding memory usage and time-space trade-offs

Interview Preparation

• Technical Interview Preparation - Systematic framework and strategies for acing technical interviews

Getting Started

Choose an algorithm pattern that interests you or start with Sliding Window for a fundamental technique that appears frequently in coding challenges. If you're preparing for interviews, check out the Technical Interview Preparation guide for a comprehensive framework.
