import java.util.Scanner;

class App {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.println("Enter a String: ");
        String word = in.nextLine().toLowerCase();
        int s = 0;
        int n = 0;
        for (int i = 0; i < word.length(); i++) {
            if (word.charAt(i) == ' ' || i == word.length() - 1) {
                System.out.print((n % 2 == 0 ? word.substring(s, i + 1).toUpperCase() : word.substring(s, i + 1)));
                s = i + 1;
                n++;
            }
        }
        in.close();
    }
