toRoman.js

/**
 * Given a positive integer, returns a string containing that integer's
 * Roman numeral representation.
 *
 * We recommend doing this work in two iterations: first supporting only
 * additive Roman numerals and then adding support for subtractive
 * Roman numerals. See the README for details.
 *
 * @example
 * toRoman(1);   // => 'I'
 * toRoman(6);   // => 'VI'
 * toRoman(152); // => 'CLII'
 *
 * @param {number} num - An integer
 * @returns {string} The input integer's Roman numeral representation
