Solution: Split Linked List in Parts

Explore how to split a singly linked list into k consecutive parts where each part’s size differs by at most one node. Learn to calculate part sizes, traverse the list, and disconnect sublists, preserving order and distributing nodes efficiently. This lesson helps you understand in-place linked list manipulation with a focus on balanced splitting strategies and related time and space complexities.

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:
