# Instructions

Given a number from 0 to 999,999,999,999, spell out that number in English.
Given a number, your task is to express it in English words exactly as your friend should say it out loud.
Yaʻqūb expects to use numbers from 0 up to 999,999,999,999.

## Step 1
Examples:

Handle the basic case of 0 through 99.

If the input to the program is `22`, then the output should be `'twenty-two'`.

Your program should complain loudly if given a number outside the blessed range.

Some good test cases for this program are:

- 0
- 14
- 50
- 98
- -1
- 100

### Extension

If you're on a Mac, shell out to Mac OS X's `say` program to talk out loud.
If you're on Linux or Windows, eSpeakNG may be available with the command `espeak`.

## Step 2

Implement breaking a number up into chunks of thousands.

So `1234567890` should yield a list like 1, 234, 567, and 890, while the far simpler `1000` should yield just 1 and 0.

## Step 3

Now handle inserting the appropriate scale word between those chunks.

So `1234567890` should yield `'1 billion 234 million 567 thousand 890'`

The program must also report any values that are out of range.
It's fine to stop at "trillion".

## Step 4

Put it all together to get nothing but plain English.

`12345` should give `twelve thousand three hundred forty-five`.

The program must also report any values that are out of range.
- 0 → zero
- 1 → one
- 12 → twelve
- 123 → one hundred twenty-three
- 1,234 → one thousand two hundred thirty-four

# Introduction

Your friend Yaʻqūb works the counter at the busiest deli in town, slicing, weighing, and wrapping orders for a never-ending line of hungry customers.
To keep things moving, each customer takes a numbered ticket when they arrive.

When it’s time to call the next person, Yaʻqūb reads their number out loud, always in full English words to make sure everyone hears it clearly.

For a shape to be a triangle at all, all sides have to be of length > 0, and the sum of the lengths of any two sides must be greater than or equal to the length of the third side.

~~~~exercism/note
We opted to not include tests for degenerate triangles (triangles that violate these rules) to keep things simpler.
You may handle those situations if you wish to do so, or safely ignore them.

In equations:

Let `a`, `b`, and `c` be sides of the triangle.
