朴素的方法，代码反而更难
import java.util.*;
public class Main{
public static void main(String[] args){
Scanner scanner = new Scanner(System.in);
while(scanner.hasNext()){
int N = scanner.nextInt();
List<Integer> list = new ArrayList<>(N);
for (int i = 0; i < N; i++) {
int var = scanner.nextInt();
if(!list.contains(var)){
list.add(var);
}
}
list.sort(new Comparator<Integer>() {
@Override
public int compare(Integer o1, Integer o2) {
return o1.compareTo(o2);
}
});
Object[] objects = list.toArray();
for(Object object : objects){
System.out.println(object);
}
}
}
}
