Farthest-first traversal

Imagine you are playing a game where you need to find a treasure hidden in a big field. You can only move by hopping from one spot to another, and you want to find the treasure as soon as possible.

Farthest-first traversal is a strategy where you hop to the spot that is farthest away from all the spots you've already been to. This means you go as far away as possible from where you started and then keep doing that until you find the treasure.

For example, if you start in the center of the field and hop to the spot that is farthest away from where you started, you might end up in a corner of the field. From there, you then hop to the spot that is farthest away from all the spots you've been to, which might take you to a different corner. You keep doing this until you find the treasure.

Farthest-first traversal is useful in computer science when you have a lot of data points and you want to find the best way to group them together based on how far apart they are. It helps you avoid overlapping and finding solutions that are not very efficient.
