<p>Additionally, if the <code>check</code> method has the flag <code>run_on_error</code> set, it will be run against the submission&rsquo;s output, even if it receives an IR/TLE/RTE/MLE verdict.
The only built-in checker that has this flag set is the <code>linecount</code> checker.</p>
<h2 id="return">Return:<a class="headerlink" href="#return" title="Permanent link"></a></h2>
<p><code>True</code> for correct output, <code>False</code> for incorrect one</p>
<p><code>check</code> can return either a <code>CheckerResult</code> object (<code>from dmoj.result import CheckerResult</code>), or a boolean (<code>case_passed_bool</code>).
A <code>CheckerResult</code> can be instantiated through <code>CheckerResult(case_passed_bool, points_awarded, feedback='')</code>.</p>
