<p>You are given a <strong>positive</strong> integer <code>n</code>.</p>
|
|
|
|
<p>Let <code>even</code> denote the number of even indices in the binary representation of <code>n</code> (<strong>0-indexed</strong>) with value <code>1</code>.</p>
|
|
|
|
<p>Let <code>odd</code> denote the number of odd indices in the binary representation of <code>n</code> (<strong>0-indexed</strong>) with value <code>1</code>.</p>
|
|
|
|
<p>Return <em>an integer array </em><code>answer</code><em> where </em><code>answer = [even, odd]</code>.</p>
|

<pre>
|
|
<strong>Input:</strong> n = 17
|
|
<strong>Output:</strong> [2,0]
|
|
<strong>Explanation:</strong> The binary representation of 17 is 10001.
|
|
It contains 1 on the 0<sup>th</sup> and 4<sup>th</sup> indices.
