定义一个链表：class Node(object): """单链表的结点""" def __init__(self, item): # item存放数据元素 self.item = item # next是下一个节点的标识 self.next = Noneclass SingleLinkList(object): """单链表""" def __init__(self): self._h

class Solution: def twoSum(self, nums: List[int], target: int) -> List[int]: for key, value in enumerate(nums): if target-value in nums[key + 1:]: return [key,nums[key+1:].index(target-value)+key+1]
