+++++++[>+++++++<-]>.---.++++++++.-----.+++++++.--------.+++..++++++.-..-.---.+++++.-.+.----. It works :/ Not very optimised though. I can’t think of any way to optimize this, although I’m sure a way exists.
Explanation:
+++++++ Add seven to cell at 0. [ Begin a loop. >+++++++ Add seven to cell at 1. < Go back to cell 0. - Decrement the counter there (soon it will reach 0). ] End loop when cell 0 reaches 0 after 7 repetitions. > Go to cell 1 which is now 49. . Print it (1). ---. Decrement 3 to get 46 (period) then print it. Afterwards, not much explanation is needed. Just add some or subtract some and repeat until everything is printed. ++++++++.-----.+++++++.--------.+++..++++++.-..-.---.+++++.-.+.----.
