Accumulate
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.
Running the tests
To run the tests run the command go test from within the exercise directory.
If the test suite contains benchmarks, you can run these with the -bench
flag:
go test -bench .
Keep in mind that each reviewer will run benchmarks on a different machine, with different specs, so the results from these benchmark tests may vary.
