<p>Given the <code>head</code> of a singly linked list and an integer <code>k</code>, split the linked list into <code>k</code> consecutive linked list parts.</p>
|
|
|
|
<p>The length of each part should be as equal as possible: no two parts should have a size differing by more than one. This may lead to some parts being null.</p>
|
|
|
|
<p>The parts should be in the order of occurrence in the input list, and parts occurring earlier should always have a size greater than or equal to parts occurring later.</p>
|
|
|
|
<p>Return <em>an array of the </em><code>k</code><em> parts</em>.</p>

<pre>
|
|
<strong>Input:</strong> head = [1,2,3], k = 5
|
|
<strong>Output:</strong> [[1],[2],[3],[],[]]
|
|
<strong>Explanation:</strong>
|
|
The first element output[0] has output[0].val = 1, output[0].next = null.
|
|
The last element output[4] is null, but its string representation as a ListNode is [].

<pre>
|
|
<strong>Input:</strong> head = [1,2,3,4,5,6,7,8,9,10], k = 3
|
|
<strong>Output:</strong> [[1,2,3,4],[5,6,7],[8,9,10]]
|
|
<strong>Explanation:</strong>
|
|
The input has been split into consecutive parts with size difference at most 1, and earlier parts are a larger size than the later parts.
