Java for LeetCode 203 Remove Linked List Elements

標籤：

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

解題思路：

JAVA實現如下：

    public ListNode removeElements(ListNode head, int val) {        ListNode root=new ListNode(val+1),temp=root;        root.next=head;        while(temp.next!=null){        if(temp.next.val==val)        temp.next=temp.next.next;        else temp=temp.next;        }        return root.next;    }
