	(1...highest).max_by { \|option\| Collatz.new(option).length }
	end

	def initialize(num)

Fill in ActiveRecord Migration Rails Versions by shell script (tested on Mac OS X)

	# Instructions
	#
	# 1. Backup your repo somewhere!
	# 2. Make sure `git stash list` is empty - that'll help debugging in case things go wrong.
	# 3. Make sure `git status` shows that you've made no changes; that'll break things right away.
	# 4. Copy and paste the code below.
	# 5. Run the `update_timestamps` function and LET IT FINISH!
	# 6. Check the results, make sure they look reasonable, and commit!
	#
	# P.S. I take no responsibility for your use of the script; I recommend understanding what it does before running it.
