Write a program <code>NOrdered</code> that takes any
number of integer command-line arguments. If they are in strictly
increasing or strictly descreasing order, it should print <code>true</code>.
Otherwise it should print <code>false</code>.

Correct answer
Template / Reference solution

public static void main(String[] args) {
int n = args.length; // for convenience
\[
int[] vals = new int[n];
for (int i=0; i<n; i++)
vals[i] = Integer.parseInt(args[i]);

// check for increasing
boolean increasing = true;
for (int i=0; i<n-1; i++) // one shorter than usual
increasing = increasing && (vals[i] < vals[i+1]);

// check for decreasing
boolean decreasing = true;
for (int i=0; i<n-1; i++) // one shorter than usual
decreasing = decreasing && (vals[i] > vals[i+1]);

System.out.println(increasing || decreasing);
