- Write a method to convert numbers into Roman numerals. Roman numerals are based on seven symbols:
| Symbol | Value |
|---|---|
| I | 1 |
| V | 5 |
| X | 10 |
| L | 50 |
| C | 100 |
| D | 500 |
| M | 1000 |
- The most basic rule is that you add the value of all the symbols: so II is 2, LXVI is 66, etc.
- The exception is that there may not be more than three of the same characters in a row. Instead, you switch to subtraction. So instead of writing IIII for 4, you write IV (for 5 minus 1); and instead of writing LXXXX for 90, you write XC.
- You also have to separate ones, tens, hundreds, and thousands. In other words, 99 is XCIX, not IC. You cannot count higher than 3,999 in Roman numerals.
