Boolean and integer variables and Conditionals =====================
Write a program `Ordered.java` that reads in three integer command-line arguments, `x`, `y`, and `z`. Define a boolean variable `isOrdered` whose value is `true` if the three values are either in strictly ascending order (`x < y < z`) or in strictly descending order (`x y z`), and `false` otherwise. Print out the variable `isOrdered` using `System.out.println(isOrdered)`.
