<div><p>Given an integer <code>n</code>, you must transform it into <code>0</code> using the following operations any number of times:</p>

<ul>
	<li>Change the rightmost (<code>0<sup>th</sup></code>) bit in the binary representation of <code>n</code>.</li>
	<li>Change the <code>i<sup>th</sup></code> bit in the binary representation of <code>n</code> if the <code>(i-1)<sup>th</sup></code> bit is set to <code>1</code> and the <code>(i-2)<sup>th</sup></code> through <code>0<sup>th</sup></code> bits are set to <code>0</code>.</li>
</ul>

<p>Return <em>the minimum number of operations to transform </em><code>n</code><em> into </em><code>0</code><em>.</em></p>

<p>&nbsp;</p>
<p><strong>Example 1:</strong></p>

<pre><strong>Input:</strong> n = 0
<strong>Output:</strong> 0
</pre>

<p><strong>Example 2:</strong></p>

<pre><strong>Input:</strong> n = 3
<strong>Output:</strong> 2
<strong>Explanation:</strong> The binary representation of 3 is "11".
"<u>1</u>1" -&gt; "<u>0</u>1" with the 2nd operation since the 0th bit is 1.
"0<u>1</u>" -&gt; "0<u>0</u>" with the 1st operation.
</pre>

<p><strong>Example 3:</strong></p>

<pre><strong>Input:</strong> n = 6
<strong>Output:</strong> 4
<strong>Explanation:</strong> The binary representation of 6 is "110".
"<u>1</u>10" -&gt; "<u>0</u>10" with the 2nd operation since the 1st bit is 1 and 0th through 0th bits are 0.
"01<u>0</u>" -&gt; "01<u>1</u>" with the 1st operation.
"0<u>1</u>1" -&gt; "0<u>0</u>1" with the 2nd operation since the 0th bit is 1.
"00<u>1</u>" -&gt; "00<u>0</u>" with the 1st operation.
</pre>

<p><strong>Example 4:</strong></p>

<pre><strong>Input:</strong> n = 9
<strong>Output:</strong> 14
</pre>

<p><strong>Example 5:</strong></p>

<pre><strong>Input:</strong> n = 333
<strong>Output:</strong> 393
</pre>

<p><strong>Constraints:</strong></p>

<ul>
	<li><code>0 &lt;= n &lt;= 10<sup>9</sup></code></li>
</ul>
