<p>This solution checks if a number is even by dividing it by 2 and comparing the result to its integer form. While functional, the use of floating-point division introduces potential inefficiencies. Replacing division with a bitwise operation (num & 1 == 0) will improve both speed and readability, avoiding potential floating-point inaccuracies. Great effort, though! With a small optimization, your solution could be even more elegant.</p>
