This repository is dedicated to solving Data Structures and Algorithms (DSA) problems using a pattern-based approach. Instead of tackling problems randomly, each solution is organized around well-known problem-solving patterns (e.g., Sliding Window, Two Pointers, Fast & Slow Pointers, Merge Intervals, Dynamic Programming, etc.)

๐Ÿ“˜ Pattern-Wise Problem Solving

Welcome to the Pattern-Wise Problem Solving repository!
This repo contains well-structured and categorized solutions to coding problems based on popular problem-solving patterns.

The goal is to master algorithms by recognizing patterns and applying them effectively across multiple problems.


๐Ÿง  Why Pattern-Based Practice?

  • Helps in quickly identifying the right approach during interviews.
  • Enhances problem-solving speed.
  • Builds deep understanding of techniques.
