Ok so this is a little weird. My code for task1 is attached to this comment, but I actually solved task2 by hand. After checking that bruteforce indeed takes longer than a second, I plotted the graph just to see what was going on, and you can immediately tell that the result is the least common multiple of four numbers, which can easily be obtained by running task1 with a debugger, and maybe read directly from the graph as well. I also pre-broke my include statements, so hopefully the XSS protection isn't completely removing them again.

blue is the broadcaster/button, yellows are flipflops, purples are nand gates and green is the output gate.
Also I abandoned scala again, because there is so much state modification going on.
