이 문제와 비슷한데, 여기서는 배열이 아닌 List이다. value가 같으면 연결을 끊고 그 다음을 연결했다. null 검사를 통해 루프를 탈출.

// C#
/**
 * Definition for singly-linked list.
 * public class ListNode {
 *     public int val;
 *     public ListNode next;
 *     public ListNode(int x) { val = x; }
 * }
 */
public class Solution {
    public ListNode DeleteDuplicates(ListNode head) {
        ListNode cmpTemp = head;
        if(cmpTemp==null)
            return head;
        while(cmpTemp.next!=null) {
            if(cmpTemp.val==cmpTemp.next.val) {
                cmpTemp.next = cmpTemp.next.next;
                continue;
            }
            cmpTemp = cmpTemp.next;
        }
        return head;
    }
}
