Algorithms

You are given a string <code>s</code> consisting of lowercase English letters.

Construct a binary string by replacing each character in <code>s</code> with the 8-bit binary representation of its ASCII value, including leading zeros, while preserving the original order of the characters.

Return <code>true</code> if the resulting binary string is a palindrome. Otherwise, return <code>false</code>.

Example 1:

<div class="example-block">
Input: s = &quot;ff&quot;

Output: true

Explanation:

<ul>
	<li>The ASCII value of <code>f</code> is 102, whose 8-bit binary representation is <code>01100110</code>.</li>
	<li>Thus, the binary string is <code>0110011001100110</code>.</li>
	<li>Since this binary string is a palindrome, the output is <code>true</code>.</li>
</ul>
</div>

Example 2:

<div class="example-block">
Input: s = &quot;leet&quot;

Output: false

Explanation:

<ul>
	<li>The ASCII values of <code>l</code>, <code>e</code>, <code>e</code>, and <code>t</code> are 108, 101, 101, and 116, respectively.</li>
	<li>Their 8-bit binary representations are <code>01101100</code>, <code>01100101</code>, <code>01100101</code>, and <code>01110100</code>.</li>
	<li>Thus, the binary string is <code>01101100011001010110010101110100</code>.</li>
	<li>Since this binary string is not a palindrome, the output is <code>false</code>.</li>
</ul>
</div>

Constraints:

<ul>
	<li><code>1 &lt;= s.length &lt;= 100</code></li>
	<li><code>s</code> consists of lowercase English letters.</li>
</ul>
