Solution: Split Linked List in Parts

Understand how to split a singly linked list into k consecutive parts where each part's size differs by at most one node. Discover the method to evenly distribute nodes, maintain list order, and handle cases with fewer nodes than parts. Learn the algorithm's time and space complexity while practicing in-place linked list manipulation.

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:
