If I have a number of list
list1 = [2,3]
list2 = [1,2]
list3 = [2,3,4]
list4 = [1,2,3]

from the corresponding list so for the above input I would get.
a = [3,2,4,1]
ofcourse there may be several set that will satisfy the problem, so a
list of list that satisfies would be good.
How do I do this in haskell? or is there a code snippet that seems to
