#The Collatz sequence is defined by the following rules on the set of positive numbers:

# n -> n/2 if n is even
# n -> 3n + 1 if n is odd

#Starting with 13, the sequence proceeds:
# 13 - 40 - 20 - 10 - 5 - 16 - 8 - 4 - 2 - 1

#Which starting number, under 1,000,000 produces the longest chain?

#by dividing the total amount bet on all the horses by the amount bet on the
#specific horse. The people who have bet on a winning horse divide up all the 
#money bet in proportion to the relative amount of their respective bets on the
