in reply to (OT) Interview questions -- your response?
I'm coming late to this here thread... But I think the point is being missed by the responses to: foreach a_item in a_array foreach b_item in b_array if a_item equals b_item put a_item in c_array end if end for end for What does this code do? @a = ( a c f r f z t ); @b = ( e c s f r f) ; @a a c f r f z t @b @c = ( e _ _ _ _ _ _ _ c _ c _ _ _ _ _ s _ _ _ _ _ _ _ f _ _ f _ f _ _ r _ _ _ r _ _ _ f _ _ f _ f _ _ ) where an underscore is ignored - read left-right-top-bottom c f f r f f If we hash either, a or b, we always will lose something- the r will be out of place, values repeated in both the a and b will overrepresented or overrepresented. What do you do about your performance problems? Cry, cus it's not going to get much better than as it's presented in the initial question. (removing items from a that aren't in b and vice versa might do some good, depending on the data.)surfing the net and other cliches....
