Learn Dart: First Step to Flutter

## Task

In this challenge, you had to create a function that returns the result of another function.


## Solution

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

```dart
num arithmeticCalculator(Function f, int x, int y){

}
```

The function name is `arithmeticCalculator` and it has three parameters. The first parameter is another function, `f`. The second parameter is an integer, `x`, and the third parameter is an integer, `y`.

You had to write a line of code that would print the result of `f` given that it was passed `x` and `y` as arguments. 

```dart
f(x,y)
```

You can find the complete solution below:

>You were required to write the code given on **line 2**.
