Customer Path Reversal

Medium

Linked List

In "Customer Path Reversal", a singly linked sequence is represented as an array in input order.

Return the sequence in reversed order as if the linked list pointers were fully reversed.

Example 1

Input:head = [18,19,20]
Output:[20,19,18]

For input head = [18,19,20], reversing the node direction makes the values appear in reverse order, so the output is [20,19,18]. Therefore, return [20,19,18].

Example 2

Input:head = [36,37,38]
Output:[38,37,36]

For input head = [36,37,38], reversing the node direction makes the values appear in reverse order, so the output is [38,37,36]. Therefore, return [38,37,36].

Constraints

  • 0 <= head.length <= 5000
  • -5000 <= head[i] <= 5000
