Solution: Split Linked List in Parts

Explore how to split a singly linked list into k consecutive parts where the sizes differ by at most one node. Understand the process of calculating part sizes, iterating through nodes, and dividing the list in-place to maintain order while distributing nodes evenly among the parts.

We'll cover the following...

Statement

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 11.

  • 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:
