ADA Random Seed of an Array
 

Here is the deal, I have an array, say array1 that I want to take a random seed of. How do I do this? Basically I want to take a random sampling of array1 and make a new array, called list that is built from these values, with no duplicates. A 3rd array would also be made, called outlist, which would be all the values in array1 that are not in list.

Thanks!
