2487 - Remove Nodes From Linked List.

Medium

You are given the head of a linked list.

Remove every node which has a node with a strictly greater value anywhere to the right side of it.

Return the head of the modified linked list.

Example 1:

Input: head = [5,2,13,3,8]

Output: [13,8]

Explanation: The nodes that should be removed are 5, 2 and 3.

  • Node 13 is to the right of node 5.
  • Node 13 is to the right of node 2.
  • Node 8 is to the right of node 3.

Example 2:

Input: head = [1,1,1,1]

Output: [1,1,1,1]

Explanation: Every node has value 1, so no nodes are removed.

Constraints:

  • The number of the nodes in the given list is in the range [1, 105].
  • 1 <= Node.val <= 105
