Lintcode6 Merge Two Sorted Arrays solution 题解

Given k sorted integer arrays, merge them into one sorted array. Given 3 sorted arrays: [ [1, 3, 5, 7], [2, 4, 6], [0, 8, 9, 10, 11] ] return [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]. 这题和merge k sorted lists 一脉相承,但是处理起来要复杂些,即linked list可以非常容易的从当前结点通过.n

class Solution { /** * @param A and B: sorted integer array A and B. * @return: A new sorted integer array */ public int[] mergeSortedArray(int[] A, int[] B) { // Write your code here int n = A.length + B.length; int[] rst = new int[n]; int a = 0; in

#include <vector> #include <iostream> #include <queue> using namespace std; /* Write a program that takes an input a set of sorted sequences and compute the union of these sequences as a sorted sequence. For example: [3, 5, 7], [0, 6, 8]

Question 23.?Merge k Sorted Lists Solution 题目大意:合并链表数组(每个链表中的元素是有序的),要求合并后的链表也是有序的 思路:遍历链表数组,每次取最小节点 Java实现: public ListNode mergeKLists(ListNode[] lists) { ListNode preHead = new ListNode(0); ListNode minNode = getMinNode(lists); ListNode tmpNode =

problem: There are two sorted arrays A and B of size m and n respectively. Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)). thinking: (1)求中位数,就是求已序数列的中间位置对应的数字,分奇偶.两个已序数组求中位数,就是求合并后的中位数. (2)采用merge sor

Merge k sorted linked lists and return it as one sorted list. Analyze and describe its complexity. 题意:对k个有序的链表进行归并排序.并分析其复杂度. /** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next; * ListNode(int x) : val(x), next(N
