+<p>You are given an array of integers <code>nums</code> of size 3.</p>
+
+<p>Return the <strong>maximum</strong> possible number whose <em>binary representation</em> can be formed by <strong>concatenating</strong> the <em>binary representation</em> of <strong>all</strong> elements in <code>nums</code> in some order.</p>
+
+<p><strong>Note</strong> that the binary representation of any number <em>does not</em> contain leading zeros.</p>
