<p>The <strong>bitwise AND</strong> of an array <code>nums</code> is the bitwise AND of all integers in <code>nums</code>.</p>

<ul>
	<li>For example, for <code>nums = [1, 5, 3]</code>, the bitwise AND is equal to <code>1 &amp; 5 &amp; 3 = 1</code>.</li>
	<li>Also, for <code>nums = [7]</code>, the bitwise AND is <code>7</code>.</li>
</ul>

<p>You are given an array of positive integers <code>candidates</code>. Evaluate the <strong>bitwise AND</strong> of every <strong>combination</strong> of numbers of <code>candidates</code>. Each number in <code>candidates</code> may only be used <strong>once</strong> in each combination.</p>

<p>Return <em>the size of the <strong>largest</strong> combination of </em><code>candidates</code><em> with a bitwise AND <strong>greater</strong> than </em><code>0</code>.</p>

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

<pre>
<strong>Input:</strong> candidates = [16,17,71,62,12,24,14]
<strong>Output:</strong> 4
<strong>Explanation:</strong> The combination [16,17,62,24] has a bitwise AND of 16 &amp; 17 &amp; 62 &amp; 24 = 16 &gt; 0.
The size of the combination is 4.
It can be shown that no combination with a size greater than 4 has a bitwise AND greater than 0.
Note that more than one combination may have the largest size.
For example, the combination [62,12,24,14] has a bitwise AND of 62 &amp; 12 &amp; 24 &amp; 14 = 8 &gt; 0.
</pre>

<p><strong class="example">Example 2:</strong></p>

<pre>
<strong>Input:</strong> candidates = [8,8]
<strong>Output:</strong> 2
<strong>Explanation:</strong> The largest combination [8,8] has a bitwise AND of 8 &amp; 8 = 8 &gt; 0.
The size of the combination is 2, so we return 2.
