将阿拉伯数字转换为罗马字符
建立一个二维数组来代表转换表 代码如下：
public class Solution {
public String intToRoman(int num) {
String[][] sss={{"I","II","III","IV","V","VI","VII","VIII","IX"},{"X","XX","XXX","XL","L","LX","LXX","LXXX","XC"},{"C","CC","CCC","CD","D","DC","DCC","DCCC","CM"},{"M","MM","MMM"}};
String res="";
String s=String.valueOf(num);
for(int i=s.length()-1;i>=0;i--){
if(s.charAt(i)=='0')continue;
else{
res=sss[s.length()-1-i][s.charAt(i)-'0'-1]+res;
}
}
return res;
}
}
