Hello, everyone, and welcome back.
In this section, we're going to continue with what we learned about interface design, but we're going
to extend into yet another data structure this time.
This data structure is called a tree or a tree.
And just like its name, it is a variation of a tree.
In this particular case, it's a variation of an energy tree.
And this data structure particularly holds strings.
This is a data structure that's very useful when you need to quickly search up different words or characters
as long as they're based on strings.
If you're unfamiliar with TREIS, I have linked in your resources a quick video that Andrew has done
going through what they are.
The key to remember here is that they are a form of energy tree, but with a very specific purpose of
helping us quickly search up words.
So check out that video that Andrea has done in the resources inside of your appendix and then come
back and we will tackle a question that involves a tri.
