Two reviewers rejected it with the following reason:
This edit deviates from the original intent of the post. Even edits that must make drastic changes should strive to preserve the goals of the post's owner.
The original post addresses the question by explaining how programming works on this condition. The original illustration of code is incorrect, and would arise misunderstanding to those who have no computer science background, therefore I made this edit. This is not a 'deviation from the original intent of the post', but a fix.
