[Solved] what is meaning and explanation of the scala code required

Question

span

“Returns the longest prefix of the list whose elements all satisfy the
given predicate, and the rest of the list.”

the list here is the ls parameter and ls.head is the first item of the list
The two lists are then assigned to packed (containing the longest prefix) and next which contains the rest. if next is empty the prefix list is returned otherwise there’s a recursive call concatenating the prefix list with the result of the recurse
