I have the following problem:

I have these 3 strings stored in an string array

array[0]: Juice Milk Yogurt
array[1]: Milk Juice Yogurt
array[2]: Yogurt Juice Milk

Since these strings have the same elements I need to remove the
redundant ones. One method is to break them into single element and
then compare them, but this is not efficient. I was wodering if
there is a better method.

Actually, I am implementing Aprori algo. of data mining and if
possible can anybody let me know which data structures to use for
such a problem.
