Dining philosophers problem

Imagine five friends at the dinner table. Between each of their plates is a bowl of spaghetti, which they all have to eat. The problem is that in order to eat the spaghetti, each of them needs two forks. But there are only five forks for the five friends! They have to figure out the best way to share the forks so that everyone can eat their spaghetti. This is called the "dining philosophers problem". The friends need to figure out how to use the limited number of forks in the most efficient and fair way. They have to figure out a way to take turns with the forks and decide who gets to eat first.
