Write a program to find the node at which the intersection of two singly linked lists begins. For example, the following two linked lists: A: a1 → a2 ↘ c1 → c2 → c3 ↗ B: b1 → b2 → b3 begin to intersect at node c1. Notes: If the two linked lists have…

Merge k sorted linked lists and return it as one sorted list. Analyze and describe its complexity. 解题思路: 1.先取出k个list的首元素,每个首元素是对应list中的最小元素,组成一个具有k个结点的最小堆:o(k*logk) 2.此时堆顶元素就是所有k个list的最小元素,将其pop出,并用此最小元素所在list上的下一个结点(如果存在)填充堆顶,并执行下滤操作,重新构建堆.o(logk) 3…
题意: Merge k sorted linked lists and return it as one sorted list. Analyze and describe its complexity. (Hard) 分析: 方法1: 利用做过的merge 2 sorted list,将头两个归并,结果再与下一个归并,以此类推,归并完所有. 时间复杂度分析是个小问题, merge 2 sorted list的复杂度是O(n),本以为结果就是O(n * k). 但是仔细考虑,随着归并不断进行,其…
1.合并两个排好序的list Merge Two Sorted Lists Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. 2.删除list倒数第n个元素 Remove Nth Node From End of List Given a linked list,…
