abcd
efg
(i.e., the C string "abcd\nefg")
Then the output should be
gfe
dcba
(i.e., the C string "gfe\ndcba")
Bonus points for using esoteric languages such as brainf*ck.
*EDIT:** Removed the unnecessary…

But all quines I know store their source code in a string and then replace a special character in it using something like chr and ord.
My language only has the following

I just wanted to know if it is 100% possible, if my language is turing-complete, to write a program in it that prints itself out (of course not using a file reading function)
So if the language just has the really necessary things in order to make it turing complete (I would prove that by translating…
