    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
