Problem: Split Linked List in Parts

med
30 min
Understand how to divide a singly linked list into k consecutive parts with sizes differing by at most one. Learn to handle cases where the list cannot be evenly divided by distributing nodes to earlier parts and representing empty parts as null. Practice implementing this efficient in-place algorithm to manage linked list splits while maintaining order and memory optimization.

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:

  • The number of nodes in the list is in the range [0,103][0, 10^{3}].

  • 00 \leq Node.value 103\leq 10^{3}

  • 11 \leq k 50\leq 50
