Accumulate in Perl 6
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.
exercism fetch perl6 accumulate
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.
Keep your hands off that collect/map/fmap/whatchamacallit functionality provided by your standard library! Solve this one yourself using other basic tools instead.
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
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'.
