Second is use divide and conquer. it is similar to merge sort. But the space complexity seems exceeded. Pattern of mergesort: merge(l1, l2): cur = -1; whlie(l1 && l2){ if(l1->v < l2->v) cur->next = l1 l1 = l1->

leetcode:Merge Sorted Array (合并排好序的数组) Question:Given two sorted integer arrays A and B, merge B into A as one sorted array. Note: You may assume that A has enough space (size that is greater or equal tom+n) to hold additional elements from B. The number of elements initiali...
Given two sorted integer arrays A and B, merge B into A as one sorted array. Note: You may assume that A has enough space (size that is greater or equal tom+n) to hold additional elements from B. The number of elements initialized in A and B aremandnrespectively. 解题思路: 1、合并...

leetcode-88-Merge Sorted Array Error: cannot solve it. Insert it backward, compare the bigger one. It use the advantage of backward, which is it will not make any impact to the item in front of it.
今天的笔记包含多路归并(K-way merge)与拓扑排序(Topological Sort)类型下的X个题目。其中“多路归并”在leetcode上的编号和题名分别是: 21 - 合并两个有序列表 23 - 合并k个排序列表 373 - 查找和最小的k对数字 378 - 有序矩阵中第k小的元素 而拓扑排序的练习包含以下两个部分: 排序的实现(LeetCode对应...

用一个大小为K的最小堆(用优先队列+自定义降序实现)(优先队列就是大顶堆,队头元素最大,自定义为降序后,就变成小顶堆,队头元素最小),先把K个链表的头结点放入堆中,每次取堆顶元素,然后将堆顶元素所在链表的下一个结点加入堆中。 代码语言:javascript ...
