2099.整除的尾数

import java.util.LinkedHashMap;
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner=new Scanner(System.in);
        while (true){
            LinkedHashMap<String,Integer> hashMap=new LinkedHashMap<>();
            int a= scanner.nextInt();
            int b=scanner.nextInt();
            if (a==0&&b==0){
                break;
            }
            for (int i=Integer.parseInt(a+"00");i<=Integer.parseInt(a+"99");i++){
                if (i%b==0){
                    String str=String.valueOf(i);
                    hashMap.put(str.substring(str.length()-2,str.length()),1);
                }
            }
            StringBuilder sb=new StringBuilder();
            for (String s: hashMap.keySet()){
                sb.append(s).append(" ");
            }
            System.out.println(sb.toString().trim());
        }
    }
}

记得用LinkedHashmap不然不会排序
