The power of netizens is strong. Yesterday I posted a post about an interview/PEN question. It provides many solutions for netizens. I have to admit that I wroteCodeIs so bad. Even so, it is also necessary to discuss with everyone, it is also necessary to write your own thoughts. Only in this way can we make progress and make changes to optimize our bad code. Then I sent a piece of bad code, hoping to learn more beautiful and excellent code from netizens. Test Questions Determines whet
