# Leetcode – Integer to Roman

Name: Integer to Roman
Difficulty: Medium
Description: Convert an integer to Roman Numerals

Example:

```Input: num = 3
Output: "III

Input: num = 58
Output: "LVIII"

Input: num = 1994
Output: "MCMXCIV"```

Just used a simple approach for this one, it’s self-explanatory.

``````static void repeat(string& s, int count, char c){
while(count-- > 0) s.push_back(c);
}

string intToRoman(int num) {
string res = "";

if (num >= 1000) {
repeat(res, num / 1000, 'M');
num %= 1000;
}

if (num >= 900) {
res += "CM";
num -= 900;
}

if (num >= 500) {
repeat(res, num / 500, 'D');
num %= 500;
}

if (num >= 400) {
res += "CD";
num -= 400;
}

if (num >= 100) {
repeat(res, num / 100, 'C');
num %= 100;
}

if (num >= 90) {
res += "XC";
num -= 90;
}

if (num >= 50) {
repeat(res, num / 50, 'L');
num %= 50;
}

if (num >= 40) {
res += "XL";
num %= 40;
}

if (num >= 10) {
repeat(res, num / 10, 'X');
num %= 10;
}

if (num == 9) return res + "IX";

if (num >= 5) {
repeat(res, num / 5, 'V');
num %= 5;
}

if (num == 4) return res + "IV";

if (num > 0) {
repeat(res, num, 'I');
}

return res;
}``````
