Nested Collections

Within the `Examples` directory you will find files that correlate with the `Nested Collections` lesson. You will work within this repo during the class in breakout rooms. During the lesson the instructor will notify you on which file you will be working in.

In each file you will see a collection
Below that collection you will see commented out instructions on what you are trying to implement
Write your code below the commented out instructions. These files will not implement tests so you will need to use a p before the code in order to print to your terminal.

Example:
```
names = ["bob", "linda", "joe", "sally"]
p names.upcase
```
From the CLI (command line interface) type ruby <filename.rb>

Example:
```
ruby warm_up.rb
```
