import java.util.*;
public class LeapYear {
        public static void main(String[]args) {
                Scanner sc = new Scanner(System.in);
                System.out.print("Enter Leap Year or Word Count: ");
                String input = sc.nextLine();
                if(input.equals("Leap Year")) {
                        System.out.print("Enter year: ");
                        int year = sc.nextInt();
                        if((year % 400 == 0) || (year % 4 == 0 && year % 100 != 0)) {
                                System.out.println("Leap Year");
                        } else {
                                System.out.println("Not a Leap Year");
                        }
                } else if(input.equals("word count")) {
                        System.out.print("Enter a string: ");
                        String word = sc.nextLine();
                        System.out.println("Word count is: " + (word.split(" ").length));
                }
        }
