<p>Given an integer array <code>nums</code>, return <code>true</code> if any value appears <strong>at least twice</strong> in the array, and return <code>false</code> if every element is distinct.</p>

<p><strong>Example 1:</strong></p>
<pre><strong>Input:</strong> nums = [1,2,3,1]
<strong>Output:</strong> true
</pre><p><strong>Example 2:</strong></p>
<pre><strong>Input:</strong> nums = [1,2,3,4]
<strong>Output:</strong> false
</pre><p><strong>Example 3:</strong></p>
<pre><strong>Input:</strong> nums = [1,1,1,3,3,4,3,2,4,2]
<strong>Output:</strong> true
</pre>
