class Solution {public: string intToRoman(int num) { // Start typing your C/C++ solution below // DO NOT write int main() function string result=""; string alpha[13]={"M","CM","D","CD","C","XC","L","XL","X","IX","V","IV","I"}; int val[13]={1000,900,500,400,100,90,50,40,10,9,5,4,1}; for(int i=0; i<13;i++) { while(num>=val[i]) { result+=alpha[i]; num-=val[i]; } } return result; }};- LeetCode Roman to Integer && Integer to Roman
