+--- Part Two ---
+
+Due to what you can only assume is a mistranslation (you're not exactly fluent in Crab), you are
+quite surprised when the crab starts arranging many cups in a circle on your raft -
+one million (1000000) in total.
+
+Your labeling is still correct for the first few cups; after that, the remaining cups are just
+numbered in an increasing fashion starting from the number after the highest number in your list and
+proceeding one by one until one million is reached. (For example, if your labeling were 54321, the
+cups would be numbered 5, 4, 3, 2, 1, and then start counting up from 6 until one million is
+reached.) In this way, every number from one through one million is used exactly once.
+
+After discovering where you made the mistake in translating Crab Numbers, you realize the small crab
+isn't going to do merely 100 moves; the crab is going to do ten million (10000000)
+moves!
+
+The crab is going to hide your stars - one each - under the two cups that will
+end up immediately clockwise of cup 1. You can have them if you predict what the labels on those
+cups will be when the crab is finished.
+
+In the above example (389125467), this would be 934001 and then 159792; multiplying these together
+produces 149245887792.
+
+Determine which two cups will end up immediately clockwise of cup 1. What do you get if you
+multiply their labels together?
