<h2>Test - Faulty Algorithm</h2>
<p>
In the case of a faulty algorithm, the algorithm may manage to pass some (or even most) tests, but ultimately it will fail in some cases. As long as the algorithm fails in one or more instances, the algorithm will not pass.

<strong><em><u>Note: It is HIGHLY recommended that you create a <code>new</code> instance of <code>Test</code> every time you test a new function/algorithm.</u></em></strong>
