First, attach a small example of recursion and circulation.
public static void main(String[] args) {
int recursion = recursion(1, 6, 0);
int loop = loop(1, 6, 0);
System.out.println("Output recursive result: + recursion);
System.out.println("Output loop results: "+ loop);
}

At present, many browsers have strengthened the security of HTML and require the configuration of HTTPS.
The following example is the Apache configuration HTTPS process on CentOS7.
First, generate certificates.
Using OpenSSL to generate key and certificates:
mkdir /etc/ssl/private
chmod 700 /etc/ssl/private
openssl req -x509 -nodes -days 3650 -newkey rsa:2048 -keyout /etc/ssl/private/apache-selfsigned.key -out /etc/ssl/certs/apache-selfsigned.crt
openssl dhparam -out /etc/ssl/certs/dhparam.pem 2048

A programmer can be a team. You must never think of it.
You must have used Google? Do you think this page is as simple as a programmer?
But that’s not the case. Behind the page is a service called Google Web Servers, which has hundreds of people maintaining it.
