You have decided to start a movie company. You quickly realize that the most difficult part will be writing the copyright year in Roman numerals in the credits. MiniScript to the rescue!
Write a decToRoman function that can convert any integer from 1 to 3999 into Roman numerals using standard form (including IV for 5, IX for 9, etc.). Check your work on the following test cases:
39: XXXIX
160: CLX
207: CCVII
246: CCXLVI
789: DCCLXXXIX
1009: MIX
1066: MLXVI
1776: MDCCLXXVI
2421: MMCDXXI
Hints
You will need a map that encodes the Roman letters for 1, 4, 5, 9, 10, 40, 59, 90, and so on up to 1000. Then, your function will enter a loop, looking for the biggest such value that is not bigger than your number. When you find that, add the letters to your output string, and subtract that value from your number. Repeat until the number has gone to zero.
