Problem Statement
Many language implementations come with an interactive mode. This is a command-line interpreter that reads lines from the user and evaluates these lines as statements or expressions. An interactive mode may also be known as a command mode, a read-eval-print loop (REPL), or a shell.
Show how to start this mode. Then, as a small example of its use, interactively create a function of two strings and a separator that returns the strings separated by two concatenated instances of the separator (the 3rd argument).
should return
This task is not about creating your own interactive mode.
Let's start with the solution:
