## spelling
### Instructions
In this exercise, you'll create the function `spell` that will spell a generated number.
Here are some examples of what your function should return:
- `1` -> `"one"`
- `14` -> `"fourteen".`
- `96` -> `"ninety-six"`
- `100` -> `"one hundred".`
- `101` -> `"one hundred one"`
- `348` -> `"three hundred forty-eight"`
- `1002` -> `"one thousand two".`
- `1000000` -> `"one million"`
> Only positive numbers will be tested, up to `"one million"`.
