DSA in C++

Comprehensive repository for mastering Data Structures and Algorithms (DSA) in C++. This repo is organized in a structured, folder-first way so you can learn topic by topic, read full implementations, and revise later without losing the roadmap.

Repository focus:

• C++ implementations of data structures and algorithms
• A structured learning path (topics, labs, assignments, revision)
• Code you can study deeply and run locally

Who this repository is for

This repo is useful if you are:

• learning DSA from scratch in C++
• preparing for interviews and want clean topic-wise practice
• looking for implemented data structures you can read and analyze
• a developer who wants to contribute improvements or new topics

Quick start

If you only open one folder, start here:

Data Structures and Algorithms: https://github.com/saqibbedar/dsa/tree/main/Data%20Structures%20%26%20Algorithms

How to explore this repository

Recommended way to use this repo:

1. Pick one topic folder inside Data Structures & Algorithms
2. Read the implementation and trace the logic
3. Run the code locally
4. Modify or extend the code (add operations, add tests, refactor)
5. Move to the next topic

Tip: Don’t jump across topics randomly. Go one folder at a time and keep notes.

Repository structure

Main folders you will use:

Data Structures & Algorithms

Path: Data Structures & Algorithms/

This is the main content folder. Topics are organized into separate directories, for example:

• LinkedList
• Stack
• Queue
• Priority-Queue
• Binary Search Tree
• Sorting Algorithms
• Recursion
• Iterators

Assignments

Path: Assignments/

Coursework-style assignments for practice and reinforcement.

DSA Friday Lab

Path: DSA Friday Lab/

Lab-style practice content. Good for building consistency and speed.

Quick C++ Revision

Path: Quick C++ Revision/

A compact revision area for C++ basics that are important for DSA (pointers, references, templates, STL basics).

Past Pappers

Path: Past Pappers/

Past-paper style material for revision and exam-style practice.

docker-guide

Path: docker-guide/

Notes and guidance related to using Docker for a consistent environment.

Notes

Files like NOTES.yaml and various about-this-folder.yaml files are included to keep the repo navigable and structured.

Running code locally

This repository contains multiple independent topic folders. Most files are designed to compile and run individually.

Typical compile and run commands:

g++ -std=c++17 file.cpp -o app
./app

If a folder contains multiple .cpp files that depend on each other, compile them together:

g++ -std=c++17 main.cpp other.cpp -o app
./app

If you run into missing includes or name collisions, compile one folder at a time.

Contributing

Contributions are welcome. If you are a developer, you can help by:

• fixing bugs
• improving code clarity and naming
• adding missing operations and edge case handling
• adding new topics in the same structured style
• adding small test drivers or usage examples

Contribution guidelines are available here:

• Contribute/CONTRIBUTE.yaml

General flow:

1. Fork the repository
2. Create a new branch
3. Make changes and test them
4. Open a pull request with a clear description
