# 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. ## Resources Remember to check out the Perl 6 [documentation](https://docs.perl6.org/) and [resources](https://perl6.org/resources/) pages for information, tips, and examples if you get stuck. ## Running the tests There is a test suite and module included with the exercise. The test suite (a file with the extension `.t`) will attempt to run routines from the module (a file with the extension `.pm6`). Add/modify routines in the module so that the tests will pass! You can view the test data by executing the command `perl6 --doc *.t` (\* being the name of the test suite), and run the test suite for the exercise by executing the command `prove . --exec=perl6` in the exercise directory. You can also add the `-v` flag e.g. `prove . --exec=perl6 -v` to display all tests, including any optional tests marked as 'TODO'. ## Source Conversation with James Edward Gray II [https://twitter.com/jeg2](https://twitter.com/jeg2) ## Submitting Incomplete Solutions It's possible to submit an incomplete solution so you can see how others have completed the exercise.
