Reverse Roman Numerals
In dieser CheckiO-Mission
Roman Numerals müssen Sie eine Dezimalzahl
zahl in ihre Darstellung als römische Zahl umwandeln.
Hier müssen Sie dasselbe tun, nur andersherum.
Sie erhalten eine römische Zahl als String und Ihre Aufgabe ist es, diese Zahl in die ...
| Ziffern | Wert |
|---|---|
| I | 1 (unüblich) |
| V | 5 (quinque) |
| X | 10 (decem) |
| L | 50 (quinquaginta) |
| C | 100 (centum) |
| D | 500 (quingenti) |
| M | 1.000 (mille) |
Eingabe: Eine römische Zahl als String.
Ausgabe: Die dezimale Darstellung der römischen Zahl als int.
Beispiel:
reverse_roman('VI') == 6
reverse_roman('LXXVI') == 76
reverse_roman('CDXCIX') == 499
reverse_roman('MMMDCCCLXXXVIII') == 3888
Vorbedingung:
len(roman_string) > 0
all(char in "MDCLXVI" for char in roman_string) == True
0 < reverse_roman(roman_string) < 4000
