[Leetcode] Remove Duplicates from Sorted List

Problem

Given a sorted linked list, delete all duplicates such that each element appear only once.

For example,
Given 1->1->2, return 1->2.
Given 1->1->2->3->3, return 1->2->3.

Analysis

• Use pointer operation
• If next element is repeated, then
• curr.next = curr.next.next
• Else
• curr = curr.next
