Re: Answer: How can I find the union/difference/intersection of two arrays?

[Anonymous Monk]

the problem with that method is that your @isect can contain identical elements

for example,if @a=(1,2,3,4,2) and @b=(1,2,4), your @isect will be: (1,2,2,4)

before using this method you have to make sure each element is unique in both tab
