Given a string of digits, output all the contiguous substrings of length `n` in that string.
Implement the `keep` and `discard` operation on collections. Given a collection and a predicate on the collection's elements, `keep` returns a new collection containing those elements where the predicate is true, while `discard` returns a new collection containing those elements where the predicate is false.
Reverse a string.

Every language has its own way of doing things. Groovy is no different. Our mentors will help you learn to think like a Groovy developer and how to write idiomatic code in Groovy. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in Groovy - they'll help you discover the things you don't know that you don't know.
