You are given head of a singly linked list and an integer, k. Your task is to split the linked list into k consecutive parts.

• Each part should have a size as equal as possible, with the difference between any two parts being at most $1$.

• If the list cannot be evenly divided, the earlier parts should have more nodes than the later ones.

• Any parts that cannot be filled with nodes should be represented as NULL.

• The parts must appear in the same order as in the input-linked list.

Return an array of the k parts, maintaining the specified conditions.

Constraints:

• The number of nodes in the list is in the range $[0, 10^{3}]$ ...
