Please add string commands like:
string-append*
string-join
They're pretty useful (for example in HSPL).
Here's a great tutorial for Scheme where You can find more commands (maybe some of them are also not available on SPOJ and ideone):
http://docs.racket-lang.org/reference/strings.htmlFor now using these (at least) two commands cause error which looks like:
ERROR: Unbound variable: string-append*
on ideone
or just "Unbound variable" on SPOJ.
Please let me know when these commands (or at least one of them) will be available so that I would HSPL again.
(I tried to avoid using these commands but after 88 tries I give up; I hope You will find time for it)
