Many solutions depend on the tested inputs... Is there a way to prevent it ?
I posted 2 working solutions, they're not the shortest, but at least, they work with ANY input (C0, B10...), not just the tested ones!
Almost all working solutions are just a plain lookup tables : boring.
Add some sharps and flats to the test cases.
