【leetcode】14. Merge two sorted lists 合并两个排序列表 这个题目用到了链表,实质就是将两个有序链表进行合并,合并后的链表应该也是有序的。 具体代码为: 用的是一个递归的方法,实际上效率很低,仅打败33%,对于 相当于一个构造函数,val 初值为x,next 为null.... 【LeetCode】86. Merge k Sorte
UsegetMid()the function to getmidthe node and its previous nodeprev. Settingprev->nexttoNULLdivides the linked list into two equal parts. Recursively callmergeSort(head)andmergeSort(mid)to sort the two smaller linked lists. Usemerge(head, mid)the function to merge two sorted linked lists. ...
Each recursive call will either be a base case, or will result in two future recursive calls. The first call starts off by making two calls; each of those makes four, and so forth. What does this sound like? If you thought, "a binary tree", then you're absolutely right. An easy...

Ping-pong merge demonstrates the superiority of binary- merge-based techniques over heap-based merging schemes, even in architecture independent settings. In this section, we introduce two variants, balanced and unbalanced. As we will see, the unbalanced version is important for sorting nearly ...

A parity merge takes advantage of the fact that if you have two n length arrays, you can fully merge the two arrays by performing n merge operations on the start of each array, and n merge operations on the end of each array. The arrays must be of equal length. Another way to descri...
