nextLine在这里首先读取了行的剩余部分根据文档，因此您需要再调用nextLine。
Scanner sc = new Scanner(System.in);
int t = sc.nextInt();
sc.nextLine(); // 添加了这一行
String s = sc.nextLine();
String[] arr = s.split(" ");
英文:
nextLine here reads the rest of the line first according to the docs, so you need another call to nextLine.
Scanner sc = new Scanner(System.in);
int t = sc.nextInt();
sc.nextLine(); // added
String s = sc.nextLine();
String[] arr = s.split(" ");
