    System.out.print("Enter the value of X: ");
    int X =input.nextInt();
    System.out.print("Enter the value of Y: ");
    int Y = input.nextInt();
    int output = power(X, Y);


    System.out.println(X + "^" + Y + "=" + output);
  }


  public static int power(int X, int Y) {
    if (Y != 0) {


      return (X * power(X, Y - 1));
    }
    else {
