Accumulate
Level 4
10 Points
Instructions
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.
