# The following iterative sequence is defined for the set of positive integers:
 
# n ->n/2 (n is even) n ->3n + 1 (n is odd)
 
# Using the rule above and starting with 13, we generate the following sequence:
 
# 13 40 20 10 5 16 8 4 2 1 It can be seen that this sequence (starting at 13 and finishing at 1) contains 10 terms. Although it has not been proved yet (Collatz Problem), it is thought that all starting numbers finish at 1.
 
# Which starting number, under one million, produces the longest chain?

Questions: 
-what is the criteria for a "successful" PB&J Sandwich?
-what are other variables we want to account for? e.g.:
  -minimize contamination of PB into Jelly jar and vice versa
  -make containers easy to reuse
  -assuming hands and plate are cleaner than table, prevent bread from touching table
-can we infer that the situation in the picture is also part of the consideration? i.e. the PB, Jelly, Bread are labeled, everything is within reach by the alien
-is the alien able to do actions with his hands that a normal human can (at least the ones involved in making a sandwich), especially opening a jar or the bread packaging

Assuming yes to all of the above:
