import java.util.Scanner;
import java.util.Set;
import java.util.TreeSet;
public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int N = scanner.nextInt();
Set<Integer> set = new TreeSet<>();
for (int i=0; i<N; i++) {
set.add(scanner.nextInt());
}
scanner.close();
for (Integer integer : set) {
System.out.println(integer);
}
}
}
使用TreeSet自动排序。
