Sorting

Great! Now let’s add a little logic to our method.

numbers = [5, 1, 3, 8] numbers.sort! puts numbers

- In the above example, we create a new array called
`numbers`

. - Then, we sort the array.
- Finally, we print out
`1`

,`3`

,`5`

,`8`

, the sorted array.

In Ruby, there are two sorting methods, `.sort`

or `sort!`

. The first method, `.sort`

, simply returns a sorted array while leaving the original array alone. The second method, `.sort!`

, modifies the actual array.

### Instructions

**1.**

Inside your method, add a line that calls `.sort!`

on the `arr`

array. Since it is the last line of the method, the sorted array will be returned.

Now test your work! After your method, make a new array called `numbers`

that contains a few numbers like the example above.

Call your `alphabetize`

method with your `numbers`

array as the parameter and `puts`

the result to the console.
