Implement the `accumulate` operation, which, given a collection and an operation to perform on each element of the collection, returns a new collection containing the result of applying that operation to each element of the input collection. Given the collection of numbers: - 1, 2, 3, 4, 5 And the operation: - square a number (`x => x * x`) Your code should be able to produce the collection of squares: - 1, 4, 9, 16, 25 Check out the test suite to see the expected function signature. ## Restrictions Keep your hands off that collect/map/fmap/whatchamacallit functionality provided by your standard library! Solve this one yourself using other basic tools instead. Lisp specific: it's perfectly fine to use `MAPCAR` or the equivalent, as this is idiomatic Lisp, not a library function.
