Yes.

You mean something like "In your warehouse, all parts of one set (with the same name) are guaranteed to have the same number of parts in a set."?

fix it

It should be specified if entries are valid in the sense that the numbers after "/" are the same for the same type of part.

The expected order of output isn't specified.

Thanks! Fix it.

Expected and actual arguments are flipped.

Seems to be a duplicate of RLE, and other katas about grouping sequences of identical characters.

Oh! Forgot delete "echo" at the start
