SpaceChem - No Thanks Necessary (3497/3/190)

This one took me quite a while to figure out. I knew it could be done with only 3 reactors. The bottom one was giving me the most trouble, spent a good 20 minutes at the end figuring it out because if it got 2 Na-Cl inputs in a row it would screw up. Fortunately I discovered that sending the red looping past the input section and just picking the Na he left up again if it detected that blue had an Na-Cl the time before, yeahhhhh.

Recorded solution for "No Thanks Necessary" from SpaceChem, a design-based puzzle game from Zachtronics Industries.

@benmaestro Hey thanks :D Yeah, it was pretty much a lucky fluke that got it to work finally. Them double Na-Cl's were a bitch xD I'm actually thinking of going back and finishing the game, my head just started hurting after three days of playing just this. The 20 minutes is also probably a huge underestimate >.<

Wow good job, I actually wasted hours trying to make a reactor that would sort the bottom output into Na-O and O-H, but after a nice headache I gave up and went for another approach. But you managed to do it. Very nice! In the end I managed to recycle the O2 from the first reactor to produce the Na-O so it worked with 3 reactors, but 2k more cycles than this solution :)
