Thank you for answering. I have submitted my request.

I decided to learn Rust's Nom crate. Got a nice solution up and running with Nom, only to experience that Nom is not accepted. Nom has 158+ million downloads, and I will suggest that any rustacean would consider Nom for a task like this.

Allow Rust Nom crate!

Just for completeness: My code used some unsafe blocks. After changing some data declarations and refactoring away unsafe blocks, my code runs just fine.

A point of note perhaps: I can't seem to remember any warning against unsafe blocks in the otherwise long troubleshooting article.

Thanks for the link.

I'm writing in Rust. In the Playground, I have called the specific sequence number given as error from Codewars, without problem. Also; I have run a loop from 1 to 250 without problem.

Random tests claim that my routine returns numbers that are later in the sequence, but when I run on my own hardware or in Playground, I get the expected numbers. Is there something wrong with the random tests?
