字符串排序 用例不通过
import java.util.*; public class Main { public static void main(String[] args) { Scanner sc = new Scanner(System.in); int n = sc.nextInt(); sc.nextLine(); Queue<String> pq = new PriorityQueue<>(n); for (int i = 0; i < n; i++) { pq.offer(sc.next()); } System.out.println(pq.stream().reduce((x, y) -> x + " " + y).get()); } }
为什么会有一半用例不通过啊 想知道哪些用例没通过
