CFG-CYK is a website based string checker using CFG with CYK algorithm using table filling method.

By using CFG-CYK you can:

• Checks whether a string is valid or not.
• Convert the CFG (Context Free grammar) to CNF (Chomsky Normal Form).
• Get the final triangular table from table filling method.

CFG-CYK is created using:

• Python - Python as the main programming language.
• Flask - Flask is a web framework for Python, based on the Werkzeug toolkit.
• Bootstrap - Bootstrap is a front-end framework that allows for the creation of easy and responsive web layouts.
• Heroku - Heroku is a platform as a service (PaaS) that we use to deploy our apps.
• Vercel - Vercel is a cloud platform that we use to deploy our apps.
• Docker - Docker is a platform for developing, shipping, and running our applications.
