# class ListNode: # def __init__(self, x): # self.val = x # self.next = None # # 代码中的类名、方法名、参数名已经指定,请勿修改,直接返回方法规定的值即可 # # # @param head ListNode类 # @param val int整型 # @return ListNode类 # class Solution: def deleteNode(self , head: ListNode, val: int) -> ListNode: # write code here curr=head #头节点特殊处理 if curr.val==val: head=head.next return head else: while curr: 当前节点的下一个节点需要删除,也就是需要修改当前节点的指针指向下下个节点即可 if curr.next.val==val: curr.next=curr.next.next return head curr=curr.next
