Day 14: Parabolic Reflector Dish

Megathread guidelines

Keep top level comments as only solutions, if you want to say something other than a solution put it in a new post. (replies to comments can be whatever)
Code block support is not fully rolled out yet but likely will be in the middle of the event. Try to share solutions as both code blocks and using something such as https://topaz.github.io/paste/ , pastebin, or github (code blocks to future proof it for when 0.19 comes out and since code blocks currently function in some apps and some instances as well if they are running a 0.19 beta)

C#

Obviously, you can't calculate 1 billion iterations, so the states must repeat after a while. My solution got to 154 different states and then started looping from state 92 to state 154 (63 steps). From there we can find the index in the state cache that the final state would be, and calculate the supported load from that.
