Just tested the code on every possible transformation, and it incorrectly gives labels to some transformations of tetrominoes 4-9, 11, 13, 21, and 22. Wow.
Hopefully I don't take another million years to fix this :) (more) |

@#53890 thanks! You're right, I did implement translation but forgot to mention it in the post. It was **way** easier than the two other transformations though _(which took 6 million years)_.
Also, just curious... you've solved the challenge yourself, right? (more) |

Thank you for changing your mind, haha (I'd be impressed if anyone can do the pentominoes, though!) (more) |

Fun fact (after 6 days): I haven't given up yet, and will probably post an (unoptimized) answer soon. It's that some tetrominoes are almost indistinguishable, which is **really really** annoying. Cool challenge though 🙂 (more) |

Alright, thanks for the clarification! Will give it a shot, though might not work haha. (more) |

Suppose we have a set of coordinates (like you said), would it be fine to group all the X coordinates to one set and the Y coordinates to another for the input? Does that count as partial precalculation? Just asking, not saying I'll use this 🙂 (more) |

A: Calculate the Z-array JavaScript (Node.js), 86 bytes ```js X=>{Y=[];for(i in X)Y[i]=0,X.slice(i).map((a,b)=>a-X[b]?i='':Y[i]++);return Y.slice``} ``` Attempt This Online! Using fancy notation, the time complexity is $$\sum^n{i=1}i$$ ...or $O(n^2)$, which according to this is horrible/worst haha. Defini... (more) |
