The gist is it first reads in two inputs. Then it starts the outer loop, conditioned on cell #1. Then it moves to cell #2, and starts the inner loop conditioned on cell #2, incrementing cell #3. However, there comes a -problem: at the end of the inner loop, cell #2 is zero. To solve this problem, +problem: At the end of the inner loop, cell #2 is zero. In that case, +inner loop won't work anymore since next time. To solve this problem, we also increment cell #4, and then recopy cell #4 into cell #2. +Then cell #3 is the result. ``` And that's brainfuck. Not that hard, eh? For fun, you can write your own |
