		System.out.println("Enter a String: ");
		String s = in.nextLine();
		int length = s.length();
		String word = "";
		int position = 0;
		for (int i = 0; i < length; i++) {
			char c = s.charAt(i);
			if (c != '.') {
				word = word + c;
			} else {
				position++;
				if (position % 2 == 0) {
					System.out.print("xyz.");
				} else {
					System.out.print(word + ".");
				}


				word = "";
			}
			if (i == length - 1) {
				position++;
				if (position % 2 == 0) {
					System.out.print("xyz");
				} else {
					System.out.print(word);
				}
			}
