Given an integer, convert it to a roman numeral.
Input is guaranteed to be within the range from 1 to 3999.
做个题还要查一遍千位罗马数字，忧伤。
代码如下：
public class Solution {
public String intToRoman(int num) {
String str = "";
String [] symbol = {"M","CM","D","CD","C","XC","L","XL","X","IX","V","IV","I"};
int [] value = {1000, 900, 500, 400, 100, 90, 50, 40, 10, 9, 5, 4, 1};
for (int i = 0; num!=0; i++) {
while (num>=value[i]) {
num-=value[i];
str+=symbol[i];
}
}
return str;
}
}
