## Challenge

Given a integer converts it to it’s Roman notation. E.g 14 becomes XIV

## Solution

First I was thinking about adding all conversion in a hash map but it not that will be ask in a real interview scenario.

```
class Solution:
def find_representation(self, num, one, five, ten):
# if less than 3
rep = ""
if 0:
return ""
if num <= 3:
for i in range(num):
rep += one
# four is five "minus" one
if num == 4:
rep += one + five
# five use five
if num == 5:
return five
# between five and nine use five + one(s)
if num > 5 and num < 9:
rep = five
for i in range(num - 5):
rep += one
if num == 9:
rep += one + ten
if num == 10:
rep += ten
return rep
def intToRoman(self, num: int) -> str:
thousand = self.find_representation((num % 10000) // 1000, "M","","")
hundred = self.find_representation((num % 1000) // 100, "C","D","M")
ten = self.find_representation((num % 100) // 10 , "X", "L", "C")
ones = self.find_representation(num % 10, "I", "V", "X")
return thousand + hundred + ten + ones
```
