    Given the head of a sorted linked list, delete all nodes that have duplicate numbers, leaving only distinct numbers from the original list. Return the linked list sorted as well.

    Example 1:

    Input: head = [1,2,3,3,4,4,5]

    Output: [1,2,5]

    Example 2:

    Input: head = [1,1,1,2,3]

    Output: [2,3]

    Constraints:

    • The number of nodes in the list is in the range [0, 300].
    • -100 <= Node.val <= 100
    • The list is guaranteed to be sorted in ascending order.
