<p>
The max() function returns the greater of x and y.
</p>
<p>
If the binary predicate p is given, then it will be used instead of the <
operator to compare the two elements.
</p>
<p>
For example, the following code snippet displays various uses of the max()
function:

When run, this code displays:
</p>
<pre class="code">
Max of 1 and 9999 is 9999
Max of 'a' and 'b' is b
Max of 3.14159 and 2.71828 is 3.14159</pre>
