No, I think that 250 solutions would not hurt, I just meant to explain why reranking is not done often in general. For this kata, three 6kyu votes and one 5kyu vote suggests that 6kyu might be a better overall rank. Getting in touch with admins and get someone to click the buttons might be difficult, but i can ask :)

No, not really. There are buttons for that, but changing a rank of a kata with many solutions brings DB to its knees, so it's usually not done except for some blatantly misranked, freshly approved betas. It's also not clear what rank a reranked kata should be, without moving it through the beta process again and collecting new bunch of votes (although in this specific case it is rather clear).

can't be changed, you know

nice spot, fixed

Description changed.

The algorithm terminates when original string has a length less than 2.

Additionally, the return value is unspecified if all of the letters are shared between the two names (such as LIAM/MILA, CLAY/LACY, ROAN/NORA, etc.).

Based on the reference solution, "Siblings" should be returned, but the description uses 1-based indexing, meaning that an index of 0 should be undefined.

I guess this can be closed.

Python translation removed. Performance kata's like this can't be balanced in Python. Builtins are too fast and can easily work around expected algorithms. Allowing these builtins makes it impossible for me to make this a 4 kyu problem in Python.

Python translation added. Let me know when you have solved it. If your solution is faster, I'll need it as a reference solution and I might increase the performance constraints a bit more.

ah ok I'll check it out; here are two kata's to keep you busy in the meantime:

• [Code Golf] Triangular Pyramid: Counting Parallelograms
• Thoughts in Motion: Fading Memories

I believe I tried it once, but got horrible performance. I might give it another shot.

its's still in beta, you may invalidate all solutions if it's better for the kata

I agree that it would be better, but is it worth changing after this many solutions?
I'm willing to do it if you approve of it, though I may mess something up with Java.
