剑指offer-25题-复杂链表复制
作者:互联网
题目:输入一个复杂链表(每个节点中有节点值,以及两个指针,一个指向下一个节点,另一个特殊指针指向任意一个节点),返回结果为复制后复杂链表的head。(注意,输出结果中请不要返回参数中的节点引用,否则判题程序会直接返回空)
python代码:
# -*- coding:utf-8 -*- # class RandomListNode: # def __init__(self, x): # self.label = x # self.next = None # self.random = None class Solution: # 返回 RandomListNode # 返回 RandomListNode def newpath(self, p): while(p): new = RandomListNode(p.label) new.next = p.next p.next = new p = new.next def cloneRandom(self, p): while(p): if(p.random != None): p.next.random = p.random.next p = p.next.next def split(self, p): newhead = p.next p.next = newhead.next p = newhead while(p.next): ne = p.next p.next = ne.next p = ne return newhead def Clone(self, pHead): # write code here if(pHead == None): return None self.newpath(pHead) self.cloneRandom(pHead) newhead = self.split(pHead) return newhead
