Problem: Split Linked List in Parts

med
30 min
Explore how to split a singly linked list into k consecutive parts that are as equal in size as possible. Understand how to maintain the original order, manage uneven divisions by allocating extra nodes to earlier parts, and represent empty parts with null, optimizing for in-place manipulation and efficient memory use.

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
