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.
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 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
