<p>You are given a binary array <code>nums</code> (<strong>0-indexed</strong>).</p>
|
|
|
|
<p>We define <code>x<sub>i</sub></code> as the number whose binary representation is the subarray <code>nums[0..i]</code> (from most-significant-bit to least-significant-bit).</p>
|
|
|
|
<ul>
|
|
<li>For example, if <code>nums = [1,0,1]</code>, then <code>x<sub>0</sub> = 1</code>, <code>x<sub>1</sub> = 2</code>, and <code>x<sub>2</sub> = 5</code>.</li>
|
|
</ul>
|
|
|
|
<p>Return <em>an array of booleans </em><code>answer</code><em> where </em><code>answer[i]</code><em> is </em><code>true</code><em> if </em><code>x<sub>i</sub></code><em> is divisible by </em><code>5</code>.</p>
|
|
|
|
<p> </p>
|
|
<p><strong>Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [0,1,1]
|
|
<strong>Output:</strong> [true,false,false]
|
|
<strong>Explanation:</strong> The input numbers in binary are 0, 01, 011; which are 0, 1, and 3 in base-10.
|
|
Only the first number is divisible by 5, so answer[0] is true.
|
|
</pre>
|

|
|
<p><strong>Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [1,1,1]
|
|
<strong>Output:</strong> [false,false,false]
|
|
</pre>
|
|
|
|
<p> </p>
|
|
<p><strong>Constraints:</strong></p>
|
|
|
|
<ul>
|
|
<li><code>1 <= nums.length <= 10<sup>5</sup></code></li>
|
|
<li><code>nums[i]</code> is either <code>0</code> or <code>1</code>.</li>
|
|
</ul>
