use key-based authentication to remotely log on to the server, instead of using the basic authentication mechanism (username and password ). Assume that you have created a key pair and a user name on the client and copied them to the server. PasswordAuthentication no RSAAuthentication yes PubkeyAuthentication yes 2) Change the port on which sshd will listen. We recommend that you use a port higher than 1024: Port XXXX 3) Only Protocol Version 2 is allowed: Protocol 2 4) configuration verificati

letters to be generated. If the sequence ZZ is required to be generated, the upper bound is 2. 3. A method that combines letters in the alphabet with previously generated letters into a cartesian product. Let's take a look at the Code: 1. generate an alphabet We can write the alphabet like this, for example: 1 List"A", "B", ..., "Z"); But this is poor. We use jOO λ instead: 1 2 3 4 List .rangeClosed('A', 'Z') .map(Object::toString) .toList();
