CyC2018 CS Notes (English Edition)

I made a structured, interview-focused knowledge base covering core Computer Science topics for software engineers by Translating the CyC2018 CS-Notes repo in English using AI. It took me few hours to do it in order to maintain consistency among files (internal links, code comments, context intact etc.)

This repository is designed to help you:

• Build strong DSA fundamentals
• Understand core CS subjects deeply
• Prepare for technical interviews (Google / Amazon / top MNCs)

Run Locally as a Website

One-click launch

After cloning or downloading the repo, you can start the Docsify site by double-clicking the launcher for your operating system:

• macOS: Open CS-Notes Site.command
• Windows: Open CS-Notes Site.bat

The launcher starts the local server and opens the site automatically at:

http://localhost:3000/#/

To stop the site, close the server window or press Ctrl+C in it.

Terminal

npm install
npm run docs:serve

Open:

http://localhost:3000/#/
