This is actually a valid brainf*ck program, but it results in 19, not 10.
How so? It’s only 10 increments
Because the only brainfuck instructions in your comment where a
-which decrements and 20+, each of which increments.Mine echos the first two characters from stdin, because of the commas and dots.
it's been a long time since i looked at brainfuck, but i suspect that '+' denotes an increment, and '-' denotes a decrement, so we've got one decrement and 20 increments.
