Hi,
I have this problem, I have array like this
B = [1,2] [2,1] [3,4] [3,5] [4,3] [4,5] [5,3] [5,4]
and i cant figure out how to delete dublicates like [1,2] or [2,1].
For example I want to make this array
B = [1,2] [2,1] [3,4] [3,5] [4,3] [4,5] [5,3] [5,4]
To this array
B = [1,2] [3,4] [3,5] [4,5]
Thanks in advance.
