## Description

<!-- description:start -->

<p data-end="116" data-start="0">You are given three integers <code data-end="33" data-start="30">x</code>, <code data-end="38" data-start="35">y</code>, and <code data-end="47" data-start="44">z</code>, representing the positions of three people on a number line:</p>

<ul data-end="252" data-start="118">
<li data-end="154" data-start="118"><code data-end="123" data-start="120">x</code> is the position of Person 1.</li>
<li data-end="191" data-start="155"><code data-end="160" data-start="157">y</code> is the position of Person 2.</li>
<li data-end="252" data-start="192"><code data-end="197" data-start="194">z</code> is the position of Person 3, who does <strong>not</strong> move.</li>
</ul>

<p data-end="322" data-start="254">Both Person 1 and Person 2 move toward Person 3 at the <strong>same</strong> speed.</p>

<p data-end="372" data-start="324">Determine which person reaches Person 3 <strong>first</strong>:</p>
