Search tree

A search tree is like a map that helps you get from one place to another. Imagine you are trying to get to a certain destination. You can look at a map to help you decide which route to take. A search tree is like a map, except that it is used to find an answer. For example, imagine there is a big library you are trying to find a book in. You can use a search tree to figure out where the book is. The search tree will lay out all of the different sections of the library and show you what books are in each one. That way, you can quickly move toward the book you are looking for.
