This project is a response to a coding work. The code lives in index.js, and is an Express based app. Run npm start to launch server.

It is also covered by some minimal tests found in test/. To run the tests, simply clone this repo, and run npm test.

Problem: Conference Track Management

You are planning a big programming conference and have received many proposals which have passed the initial screen process but you're having trouble fitting them into the time constraints of the day -- there are so many possibilities! So you write a program to do it for you.

• The conference has multiple tracks each of which has a morning and afternoon session.
• Each session contains multiple talks. Morning sessions begin at 9am and must finish by 12 noon, for lunch.
• Afternoon sessions begin at 1pm and must finish in time for the networking event.
• The networking event can start no earlier than 4:00 and no later than 5:00. No talk title has numbers in it.
• All talk lengths are either in minutes (not hours) or lightning (5 minutes).
• Presenters will be very punctual; there needs to be no gap between sessions.

Note that depending on how you choose to complete this problem, your solution may give a different ordering or combination of talks into tracks. This is acceptable; you don’t need to exactly duplicate the sample output given here.
