Learn Dart for free with this interactive course. Dart is a clean, simple, class-based, object-oriented language with more structure than JavaScript, the programming language it's heavily based on. However, you can't have a conversation about Dart without mentioning Flutter. 

Flutter is Google's mobile UI framework for crafting high-quality native interfaces on iOS and Android. Flutter applications are written using the Dart programming language, which has helped make Dart a beloved language by the developer community. Before you can start fluttering out Flutter applications, you must learn Dart. This course will help you learn the fundamentals of Dart and start your journey to learning Flutter.

Learn Dart: First Step to Flutter

# Task

In this challenge, you had to create a nested function `max` which would help its parent function `mainMax` to compute the maximum of three numbers.


# Solution

A skeleton of the `mainMax` function was already provided for you. Let's look it over.

```dart
int mainMax(int a, int b, int c) {
  
}
```

`mainMax` takes three parameters of type `int` and returns a value of type `int`.

Let's go over the step-by-step process for writing the `max` function.

* `max` is intended to break down the bigger problem into a smaller one. While `mainMax` returns the maximum of three numbers, `max` returns the maximum of two of them. This means that it will take two parameters of type `int` and return the greater of the two. To find the maximum of two numbers, a simple `if-else` expression can be used.

```dart
int max(int x, int y) {
    if(x > y){
      return x;
    } else{
      return y;
    }  
 }
```

* As for the return value of `mainMax`, we simply needed to call the `max` function. The first argument will be one of the three numbers passed to `mainMax` and the second argument will be the maximum of the remaining two. To get the second argument, we will use the `max` function again as it returns the maximum of two numbers.

```dart
return max(a,max(b,c));
```
