Yes, Nature loves symmetry. Though man discovered mathematics to solve real life and abstract problems, the Nature also obeys some mathematical rules. And sometimes, we all come to a very strange understanding seeing the unsolved mysteries of mathematics. One of that mysteries is the Collatz Conjecture or the 3n+1 conjecture .      This is nothing but a very simple procedure which we can apply to any number. But the fact all the numbers tested on this procedure come to the same output result. Let's say, we have a number N .  If it is odd then multiply it by 3 and add 1, meaning 3N+1 . And if it's even then divide it by two or calculate N/2 . And follow this steps again and again.     let's take any number 19. Odd number so 3*19+1 = 58. It is even so calculate 58/2 = 29. Now odd 3*29+1 = 88 and so on... 88 /2 =  44                   44 /2 =  22 22 /2 =...

 PHP is a very commonly used language for backend web development. This is used to make dynamic websites with a database connection. Now there are two types of request that can be sent to a PHP file GET and POST.

In these situations we have another way to send request and receive response from the PHP file. It can be done through Ajax or XMLHttp request. Normal Javascript can be used to write a code for AJAX but I will recommend jQuery to do this task as it is time saving and less code have to be written.  At first include the jQuery CDN link above the closing </BODY> tag . You can get it from here--> <script src="https://code.jquery.com/jquery-3.6.0.min.js" integrity="sha256-/xUj+3OJU5yExlq6GSYGSHk7tPXikynS7ogEvDej/m4="...
