<p>Write a function that takes an unsigned integer and returns the number of &#39;1&#39; bits it has (also known as the <a href="http://en.wikipedia.org/wiki/Hamming_weight" target="_blank">Hamming weight</a>).</p>
<p>Write a function that takes&nbsp;the binary representation of an unsigned integer and returns the number of &#39;1&#39; bits it has (also known as the <a href="http://en.wikipedia.org/wiki/Hamming_weight" target="_blank">Hamming weight</a>).</p>

<ul>
<li>Note that in some languages, such as Java, there is no unsigned integer type. In this case, the input will be given as a signed integer type. It should not affect your implementation, as the integer&#39;s internal binary representation is the same, whether it is signed or unsigned.</li>
<li>In Java, the compiler represents the signed integers using <a href="https://en.wikipedia.org/wiki/Two%27s_complement" target="_blank">2&#39;s complement notation</a>. Therefore, in <strong>Example 3</strong>, the input represents the signed integer. <code>-3</code>.</li>
