大神。请问Write a recursive function, equivalence, of the predicate that tests whether two sets contain the same elements. Note that the two lists representing the sets may be arranged in different orders, so you cannot just use EQUAL. You will need to make use of “REMOVE” for the definition of the recursive function.

不只用equal应该怎么做?
