摘要： Question： A linked list is given such that each node contains an additional random pointer which could point to any node in the list or null. Return a 阅读全文

摘要： Question： Given a sorted linked list, delete all nodes that have duplicate numbers, leaving only distinct numbers from the original list. For example, 阅读全文

摘要： Question： Given a sorted linked list, delete all duplicates such that each element appear only once. For example, Given 1->1->2, return 1->2. Given 1- 阅读全文

摘要： Question： Sort a linked list in O(n log n) time using constant space complexity. Tips：给一个单链表按照val进行排序。 思路：题目要求时间复杂度为nlog（n） 这是归并排序的时间复杂度，即采用分治的方法进行排序。 阅读全文
