OCaml

Functional programming is a paradigm that builds complete applications by breaking down programs into constituent functions that empowers developers to build fast, bug-resistant applications.

You’ll be introduced to functional programming with illustrative examples contrasting the more widely used imperative programming paradigm. You’ll review lambda calculus as an introduction to expressions, the building blocks of functional programs. You’ll continue with abstractions and complex data types before exploring common computation patterns. Next, you’ll learn how dataflows create whole programs out of existing functions. Finally, you’ll finish by applying your functional programming knowledge to various real-world scenarios. At each step, you’ll learn OCaml and Haskell, while contrasting imperative programming with Java.

By the end of this course, you’ll be prepared to use functional programming in your daily work and have the framework to know when to use either imperative or functional paradigms.

# Challenge 1: Calculating max in functional style
The following imperative code calculates the maximum of three given variables by repeatedly updating `max_number`:
 
```java
int x = 10;
int y = 2;
int z = 5;

int max_number = x;
if (max_number < y) {
   max_number = y;
}
if (max_number < z) {
   max_number = z;
}
```

Write the following code in a functional style in OCaml.
