in reply to Union, Intersection, and Difference between Arrays

If you are going to play, it is worthwhile trying to extract the functionality into functions. Then if it is useful to someone they can just call your functions.

Also if one element has duplicate elements but the other does not, then the element will show up in your intersection which it should not. Which underscores the value of writing functions in the first place. If you cut and paste the above, then discovered the bug, you would likely have repeated the bug all over. By contrast if you wrote functions then you would have limited the effort of fixing the bug just to the key functions where it appeared...
