Remove Linked List Elements

Remove all elements from a linked list of integers that have value val.

Example

Given: 1 --> 2 --> 6 --> 3 --> 4 --> 5 --> 6, val = 6

Return: 1 --> 2 --> 3 --> 4 --> 5

等于给定的val，就跳过。

public class Solution {
    public ListNode removeElements(ListNode head, int val) {
        ListNode ll=new ListNode(0);
		ll.next=head;
		ListNode t=ll;
		while(t.next!=null){
			if(t.next.val==val)
				t.next=t.next.next;
			else
				t=t.next;
		}
		return ll.next;
    }
}
