Create a function taking a positive integer as its parameter and returning a string containing the Roman Numeral representation of that integer.
Modern Roman numerals are written by expressing each digit separately starting with the left most digit and skipping any digit with a value of zero. In Roman numerals 1990 is rendered: 1000=M, 900=CM, 90=XC; resulting in MCMXC. 2008 is written as 2000=MM, 8=VIII; or MMVIII. 1666 uses each Roman symbol in descending order: MDCLXVI.
Example:
solution(1000); // should return 'M'
solution(1000) # should return 'M'
solution(1000) # should return 'M'
solution(1000) # should return 'M'
solution 1000 -- should return "M"
conversion.solution(1000); //should return "M"
solution(1000); // should return 'M'
solution(1000); // should return "M"
solution(1000); // should return "M"
RomanConvert.Solution(1000) -- should return "M"
solution(1000) // should return "M"
solution(1000) # should return "M"
solution(1000) # should return "M"
solution(1000); // => "M"
solution(1000) # should return "M"
romanEncoder(1000) -- should return 'M'
Roman.encode(1000) // should return "M"
