Define two functions named <tt>rangesize</tt>.
<ol>
<li>
<tt>int rangesize(int start, int end)</tt> <br> This function should return the number of integers in the "inclusive" set
$\{\textrm{start}, \textrm{start}+1, \dotsc, \textrm{end}\}$, which is <tt>end - start + 1</tt>. (e.g. there are
3 integers in the inclusive set of integers from 4 to 6)
<li>
<tt>double rangesize(double start, double end)</tt> <br> This function should return the <strong>length</strong> of the
interval $[\textrm{start},\textrm{end}]$ of real numbers, which is <tt>end - start</tt>.
</ol>

Java test suite

C++ test suite
json list of stdin/args tests
e.g. [{"stdin":"hi", "args":["4", "5"]}, {"stdin":"noargs"}]
to just run once with no input use [{}]
