 <p>By continuously multiplying the last digit to the variable $y$, we can get the number in reverse order.</p>
 <p>In the code implementation, we can repeatedly "take out" the last digit of $x$ and "add" it to the end of $y$, loop until $y \ge x$. If at this time $x = y$, or $x = y / 10$, then $x$ is a palindrome.</p>
 <p>The time complexity is $O(\log_{10}(n))$, where $n$ is $x$. For each iteration, we will divide the input by $10$, so the time complexity is $O(\log_{10}(n))$. The space complexity is $O(1)$.</p>
