Data Structures & Algorithms (DSA) — Concise Guide

GitHub topics: #c #dsa #algorithms #datastructures

Introduction

This repository contains concise, well-documented C implementations of core data structures and algorithms. It is focused on formative learning: short, clear examples paired with complexity notes and small exercises that build practical algorithmic skills. Use this guide to follow a short, structured study path and practice problem-solving with annotated code.

Quick Summary

Topic	Folder	What to expect
Data Structures	linkedlist/, double_Linked_List/, tree/	Implementations and basic operations
Algorithms	Leetcode/, DAA/	Problem solutions, search, sort, graph, DP
Notes & Practice	DSA COURSE/, PATTERSNS/	Course notes, pattern practice

Key Points

• Start with file00.c in each folder to learn the core idea.
• Each example includes complexity notes; verify Big O before optimizing.
• Compile with gcc -g filename.c -o filename.exe and run the produced executable.
• Use Leetcode/ for practice problems and DAA/ for analysis examples.
