Challenge: Remove Duplicates from a Linked List

Try to solve the Remove Duplicates from a Linked List problem.

We'll cover the following


Given the head of a singly linked list, remove any duplicate nodes from the list in place, ensuring that only one occurrence of each value is retained in the modified list.


Let n be the number of nodes in a linked list.

  • 00 \leq n 500\leq 500

  • 5×103-5 \times 10^3 \leq Node.value 5×103\leq 5\times 10^3
