Need Help??

in reply to Re: Re: Set Operators
in thread Set Operators

Does anyone know how the exists function is implemented for arrays? Is it the equivalent of a linear search through the array, or is it more interesting? Essentially, does it have a worst case time complexity better than N? Oops. Didn't read that very carefully. Thought you could do an exists on a value, not an index.
