1002 写出这个数 (20 分)

思路：首先求和，再把各位的和转换为字符串，最后用数字映射出对应的拼音。

public class Main{
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        String str = sc.nextLine();
        String[] strs = {"ling", "yi", "er", "san", "si", "wu", "liu", "qi", "ba", "jiu"};
        char[] chr = str.toCharArray();
        int sum =0;
        for(char c :chr){
            int x = c - '0';
            sum = sum + x;
        }
        String sums = String.valueOf(sum);
        char[] chars = sums.toCharArray();
        StringBuilder sb = new StringBuilder();
        for(char c : chars){
            int x = c -'0';
            sb.append(strs[x] + ' ');
        }
        sb.deleteCharAt(sb.length() -1);
        System.out.print(sb.toString());
         
    }
}
