Widest Vertical Area Between Two Points Containing No Points
<p>Given <code>n</code> <code>points</code> on a 2D plane where <code>points[i] = [x<sub>i</sub>, y<sub>i</sub>]</code>, Return<em>&nbsp;the <strong>widest vertical area</strong> between two points such that no points are inside the area.</em></p>

<p>A <strong>vertical area</strong> is an area of fixed-width extending infinitely along the y-axis (i.e., infinite height). The <strong>widest vertical area</strong> is the one with the maximum width.</p>

<p>Note that points <strong>on the edge</strong> of a vertical area <strong>are not</strong> considered included in the area.</p>
