 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

+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.
