1) What is a programming challenge?

A programming or coding challenge is a competitive programming contest, where you would be required to solve multiple coding problems around certain themes. These contests are usually time based, and involve problems across categories like Data Structures, Algorithms, Bot Challenges, Artificial Intelligence, Machine Learning etc.

2) What is a hackathon? How is it different from a coding challenge?

A hackathon is a gathering where programmers code collaboratively over a time period ranging from a few hours to a few days, as part of a competitive programming contest. The idea of a hackathon is usually to build something from scratch that can solve or assist the problems mentioned in the theme.

A coding challenge usually has a set problem statement with a fixed solution, whereas a hackathon is theme based. Participants are required to create a solution that best fits the theme, and there is no straight-forward answer to a question.
