<p>Given two integers <code>left</code> and <code>right</code> that represent the range <code>[left, right]</code>, return <em>the bitwise AND of all numbers in this range, inclusive</em>.</p>
 
<p>&nbsp;</p>
<p><strong class="example">Example 1:</strong></p>
 
<pre>
<strong>Input:</strong> left = 5, right = 7
<strong>Output:</strong> 4
</pre>
 
<p><strong class="example">Example 2:</strong></p>
 
<pre>
<strong>Input:</strong> left = 0, right = 0
<strong>Output:</strong> 0
</pre>
 
<p><strong class="example">Example 3:</strong></p>
 
<pre>
<strong>Input:</strong> left = 1, right = 2147483647
<strong>Output:</strong> 0
</pre>
 
<p>&nbsp;</p>
<p><strong>Constraints:</strong></p>
