- 截取最后一个单词
- 计算长度
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
while (sc.hasNext()) {
String input = sc.nextLine();
String lastWorld = input.substring(input.lastIndexOf(" ") + 1);
System.out.println(lastWorld.length());
}
}
}
(为什么这么简单的题目,难度是较难?)
