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 strings:

• "cat", "Dog", "b4t", "gO"

And the operation:

• upcase a string

Your code should be able to produce the collection of strings:

• "CAT", "DOG", "B4T, "GO"

Check out the test suite to see the expected function signature.

Keep your hands off that collect/map/fmap/whatchamacallit functionality provided by your standard library! Solve this one yourself using other basic tools instead.

Look for a stub file having the name accumulate.go and place your solution code in that file.

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 and --benchmem flags:

go test -v --bench . --benchmem

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.
