Merged.

As the author of the groovy translation, I second this.

Please, aprove the Groovy Fork

Changes in Sample Tests:

• Fixed the order of arguments in assertions

JUnit assertion Assertions.assertEquals(expected, actual) takes the EXPECTED value as the FIRST argument and the actual as the second.

The implementor of the initial Groovy translation did this the other way around and assertion failure will result in an incorrect message. For instance, if we hardcode the return value of decode() function as 'Boo', test-failure message will be

expected: <Boo> but was: <hello>

instead of proper failure message

expected: <hello> but was: <Boo>

Changes in Random Tests:

• Minor refactorings with no impact on the test behavior

Awesome kata! Thanks

Please review and approve. Note: it's my very first translation, and if I missed something, I would appreciate your suggestions.

It fails since digitize(0L) will return an empty array instead of returning {0}

• You should never check for cycle in (1), as you are at best removing dependencies from the graph.
• Instead of keeping track of current dependencies and formula in (2) and rolling back to it when a cycle is found, another option is to verify for a pending cyclic graph upfront.

you need to filter the children based on if a child is in santas list or not.

Additionally, the problem statement says that it must be case sensitive i think

Im a begginer but in my opinion its a great solution

@dinglemouse raised this already, Thanks for pointing it anyway )
