Comment (by Johannes Hoppe):
Matt, great work. I believe it is best to merge all lists at once and not
sequentially as I did. Based on your work, I would suggest to simply use
the algorithms implemented in Python. Therefore the whole merge function
can be replaced with a simple one liner:
{{{
import heapq
from collections import OrderedDict
def merge(*sublists):
return list(OrderedDict.fromkeys(heapq.merge(*sublists)))
# >>> merge([3],[1],[1,2],[2,3])
# [1, 2, 3]
}}}
