- There are 7 valid single character Roman numerals, with the following values:
- Character | Value
- --------- | ----:
- I | 1
- V | 5
- X | 10
- L | 50
- C | 100
- D | 500
- M | 1000
- ## Input
- - A single character, which will always be one of `IVXLCDM`.
- ## Output
- - The corresponding value.
- ## Test cases
- As there are only 7 valid inputs, the list of test cases is exhaustive.
- Test cases are in the format `"input" : output`.
- ```text
- "I" : 1
- "V" : 5
- "X" : 10
- "L" : 50
- "C" : 100
- "D" : 500
- "M" : 1000
- ```
