Hi!
I'm very new to Racket and the lisp family generally, and very slowly starting
to get an idea how everything works together.
Now my very first question ;)
If I have a list of string's, how can i recursivly iterate over that list and
compose a single string out of the elements of that list?
I prepared a simple example, so hopefully you can understand what I'm talking
about:
(define mylist '("hello" "darkness" "my" "old" "fiend"))
(for-each (lambda (elem)
(displayln elem)
)
mylist)
It prints out every element of mylist as I expect in a new line.
But what if I want to collect all strings into one single string, so that I can
get "hellodarknessmyoldfriend"?
I think I can use string-append, right?
But how could I do that? Is there a idiomatic way to do that in Racket?
Thank you very much for every input.
Gregor
