After you have added a few kata to a collection you and others can train on the kata contained within the collection.

He said sample test. Sample test examples can be seen.
Are you sure there is no such expression (-2k-3)^3 => -8k^3-36k^2-54k-27?
Tests are not good enough to catch faulty solutions. There should really be more random tests, and some good fixed tests.
It is not established that which direction of

problem, in the sample test, it's write this:
(-20k-3)^3 => -8k^3-36k^2-54k-27but the corect result is this:
