You are given an integer <code>n</code>.

Return <code>true</code> if its binary representation contains exactly one adjacent&nbsp;pair of&nbsp;set bits, and <code>false</code> otherwise.

&nbsp;
Example 1:

<div class="example-block">
Input: n = 6

Output: true

Explanation:

<ul>
	<li>Binary representation of 6 is <code>110</code>.</li>
	<li>There is exactly&nbsp;one adjacent pair of set bits (<code>&quot;11&quot;</code>). Thus, the answer is <code>true</code>​​​​​​​.</li>
</ul>
</div>

Example 2:

<div class="example-block">
Input: n = 5

Output: false

Explanation:

<ul>
	<li>Binary representation of 5 is <code>101</code>.</li>
	<li>There is no&nbsp;adjacent pair of set bits. Thus, the answer is <code>false</code>​​​​​​​.</li>
</ul>
</div>

&nbsp;
Constraints:

<ul>
	<li><code>0 &lt;= n &lt;= 105</code></li>
</ul>

You are given an integer n.

Return true if its binary representation contains exactly one adjacent pair of set bits, and false otherwise.

 

Example 1:

Input: n = 6

Output: true

Explanation:

 * Binary representation of 6 is 110.
 * There is exactly one adjacent pair of set bits ("11"). Thus, the answer is true .

Example 2:

Input: n = 5

Output: false

Explanation:

 * Binary representation of 5 is 101.
 * There is no adjacent pair of set bits. Thus, the answer is false .

 

Constraints:

 * 0 <= n <= 105
