Simulation can be.

"The basic symbol of the Roman numeral has I (denotes decimal number 1), V (denotes 5), X (denotes ten), L (denoted by a), C (for the millions), D (denotes a), M (denotes 1000). "– Roman numeral (Baidu Encyclopedia)

Code：

C++:

Class Solution {Private:int val[13] = {$, 5, 9, 400,100, +, +, 40,10,,, 4,1};string syb[13] = {"M", "CM", "D" , "CD", "C", "XC", "L", "XL", "X", "IX", "V", "IV", "I"};p ublic:string inttoroman (int num) {string Roman;int I = 0, K;while ( num > 0) {k = Num/val[i];while (k--) {Roman + Syb[i];num-= Val[i];} i++;} return Roman;};

Java:

public class Solution {    private int[] val = {$, 5,            9,,            4,            1
   
    };    Private string[] Syb = new string[] {            "M", "CM", "D", "CD",            "C", "XC", "L", "XL",            "X", "IX", "V", "IV",            " I "    };    Public String inttoroman (int num) {        StringBuilder Roman = new StringBuilder ();        int i = 0, K;        while (num > 0) {            k = num/val[i];            while (k--> 0) {                roman.append (syb[i]);                num-= Val[i];            }            i++;        }        return roman.tostring ();    }}
   

Python:

Class solution:    # @return A string    def inttoroman (self, num):        val = [            100, 90, 50 , Max,            9, 5, 4,            1            ]        syb = [            "M", "CM", "D", "CD",            "C", "XC", "L", "XL",            "X", "IX", "V", " IV ",            " I "            ]        roman = '        i = 0 while  num > 0: For            _ in range (num//val[i]):                Roma n + = syb[i]                num-= val[i]            i + = 1        return Roman
