Hello reviewers, I hope that you find this addition interesting.

The downside is that it requires a lot of setup to get to the enjoyable part (from MemoryAllocatorSplit to the end)

Could you please confirm whether this algorithm is suitable for this project? so I can start applying the typing changes proposed by the bot (some of them are not trivial).

I am willing to listen to your proposals. I am open to remove unnecessary parts if your consider it
