<p>Maybe you see that you will choose the third method without hesitation, moving your own brain, the first two methods are also useful D! =================== =========================</p>
<p>Some of the code that calls the function in the CS is like this:</p>
<p>In this routine, you can test the first and third solutions.</p>
