Roman Numeral Converter

算法实现功能是:将给定的数字转换成罗马数字,所有返回的 罗马数字 都应该是大写形式。

参考的资源有:Roman Numerals ; Array.splice() ; Array.indexOf() ; Array.join();

function convert(num) {var nums = [1000,900,500,400,100,90,50,40,10,9,5,4,1];var romans =["m","cm","d","cd","c","xc","l","xl","x","ix","v","iv","i"];var str = '';nums.forEach(function(item,index,array){while(num >= item){str += romans[index];num -= item;}});return str.toUpperCase();
}convert(36);
