📚 Competitive Programming Handbook

The Competitive Programming Handbook is a curated resource designed to provide KNIT Sultanpur students and the wider programming community with a structured pathway to mastering competitive coding. Covering essential topics from basic algorithms to complex problem-solving strategies, the handbook serves as both a learning guide and a reference tool.

The handbook includes:

• Core algorithms and data structures explained in a simple and practical manner. 🧠
• Problem-solving techniques drawn from real competitive programming contests. ⚡
• Set of practice problems in each module to reinforce learning. 📝
• Illustrative examples to enhance understanding. 🌟
• A compilation of useful resources for further learning. 🔗

💻⚙️ Development environment installation

You can set up the development environment in two ways:

1. Using Docker (Recommended)
2. Direct Installation (Manual)

Prerequisites

• For Docker: Docker installed on your system, refer installation guide.
• For Direct Installation: You need first install Ruby and Jekyll, see Installation for details.

1. Using Docker (Recommended)

Follow these steps to set up and preview the project using Docker:

1. Generate the Gemfile.lock file:

Use below command to create Gemfile.lock file as per your system's configuration:

• For MacOs/Linux:

  docker run --rm -v "$PWD":/usr/src/app -w /usr/src/app ruby:latest bundle install

• For Windows(Command Prompt):

   docker run --rm -v "%cd%":/usr/src/app -w /usr/src/app ruby:latest bundle install ⁠

• For Windows(Powershell):

  docker run --rm -v "${PWD}:/usr/src/app" -w /usr/src/app ruby:latest bundle install

2. Build Docker image:

   docker-compose build

3. Start the local development server:

   docker-compose up

2. Direct Installation (Manual)

Follow these steps if you prefer to set up the project manually:

1. Install dependencies using Bundler:

   bundle install --path vendor/bundle

2. Start the local development server:

   bundle exec jekyll serve

Local Preview

1. Start development server:

   • For Docker, run docker-compose up to start development server.
   • For Direct, run bundle exec jekyll serve to start the development server.

2. Local Preview:

   • Visit http://localhost:4000/ to preview site.
