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.
