<p>Given a signed 32-bit integer <code>x</code>, return <code>x</code><em> with its digits reversed</em>. If reversing <code>x</code> causes the value to go outside the signed 32-bit integer range <code>[-2<sup>31</sup>, 2<sup>31</sup> - 1]</code>, then return <code>0</code>.</p>

<p><strong>Assume the environment does not allow you to store 64-bit integers (signed or unsigned).</strong></p>

<p><strong class="example">Example 1:</strong></p>

<strong>Output:</strong> 321
