 # QUIZ:
 #   How do you sort "ary" so equal objects stay in the same relative order to each other?
 #   "ary" should be sorted by the first element of each entry.
 #   Try now: http://tryruby.org/

 # HINT:
 #   ary.sort_by { |e| e[0] }  is not the solution
 #   Here is a solution: https://gist.github.com/knugie/32ec406f6848baf67f21
