203.移除链表元素

用了创建虚拟头结点的方法，比较简单

class Solution:
    def removeElements(self, head: ListNode, val: int) -> ListNode:
        dummy_head = ListNode(next = head)
        cur = dummy_head
        while (cur.next != None):
            if(cur.next.val == val):
                cur.next = cur.next.next
            else:
                cur = cur.next
        return dummy_head.next
 
emp1 = solution1()
head=[1,2,6,3,4,5,6]
val = 6
emp1.removeElements(head, val)
#输出：[1,2,3,4,5]
