<p>Split <code>nums</code> into two arrays <code>A</code> and <code>B</code> using the following rule:</p>

<ul>
<li>Elements at <strong>prime</strong> indices in <code>nums</code> must go into array <code>A</code>.</li>
<li>Elements at <strong><span data-keyword="prime-number">prime</span></strong> indices in <code>nums</code> must go into array <code>A</code>.</li>

<p>A <strong>prime</strong> number is a natural number greater than 1 with only two factors, 1 and itself.</p>
