给定一个list, 将所有小于x的node放到左边,剩下的保持原样。 问题解决: 闲的无聊,用c++和python都做了一遍。 代码如下: #Definition for singly-linked list.#class ListNode(object):#def __init__(self, x):#self.val = x#self.next = NoneclassSolution(object):defpartition(self, head, x):""":t...
【leetcode】86. Partition List 题目如下: Given a linked list and a valuex, partition it such that all nodes less thanxcome before nodes greater than or equal tox. You should preserve the original relative order of the nodes in each of the two partitions. Example: Input: head = 1->4->...
