# Roman numerals TDD kata
Test-driven development is a software development process that
basically puts writing a failing unit test before modifying your
production code. This repository provides scaffolds for various
programming languages for hassle-free first steps in the world
of TDD by solving a simple task.
# The task
Your task is the following: Practicing test-driven development,
implement a function that converts Arabic numbers (1-3999) to
Roman numerals.
If your memory of Roman numerals is a little foggy, you can head over
to [wikipedia](https://en.wikipedia.org/wiki/Roman_numerals)
or refer to this conveniently placed table:
| Ones | | Tens | | Hundreds | | Thousands |
|----------|---|-----------|---|------------|---|------------|
| 1 = I | | 10 = X | | 100 = C | | 1000 = M |
| 2 = II | | 20 = XX | | 200 = CC | | 2000 = MM |
| 3 = III | | 30 = XXX | | 300 = CCC | | 3000 = MMM |
| 4 = IV | | 40 = XL | | 400 = CD | | |
| 5 = V | | 50 = L | | 500 = D | | |
| 6 = VI | | 60 = LX | | 600 = DC | | |
| 7 = VII | | 70 = LXX | | 700 = DCC | | |
| 8 = VIII | | 80 = LXXX | | 800 = DCCC | | |
| 9 = IX | | 90 = XC | | 900 = CM | | |
You can combine the numbers listed above, ordering larger to smaller
numbers left to right. Here are a few examples:
* 407 = CDVII
* 2017 = MMXVII
* 3888 = MMMDCCCLXXXVIII
