Trees and Recursion

This lesson introduces recursion, a powerful new problem-solving strategy.

Next we'll continue understanding Kotlin objects by exploring companion objects.

Next we'll investigate how to enable encapsulation through visibility modifiers and setters and getters.

Next we'll learn how to use lists, a linear data structure but one that is a bit more useful than the arrays that we've been working with so far.

This lesson may be the most important of the entire course, since it shows you how to use other people's code!

How many problems can nothing cause? Quite a few! We'll learn more about the nothing that is a huge problem in this lesson.

Let's meet a new type of data and our first example of an object.

As we begin writing algorithms, let's stop and discuss how to organize our code into reusable units called functions.

One of the things that makes computers so powerful is their ability to make decisions. We'll explore that capability in our programs in this lesson.

Our journey continues as we examine how we can manipulate the data stored by variables in our programs.
