When sorting arrays, merge sort requires additional scratch space proportional to the size of the input array. Merge sort is relatively simple to code and offers performance typically only slightly below that of quicksort. Previous: Heap Sort ...
1.介绍 归并排序(MergeSort)是利用归并的思想实现的排序方法,该算法采用经典的分治策略(分治法将问题分(divide)成一些小的问题然后递归求解, 而治(conquer)的阶段则将分的阶段得到的各答案“修补”在一起,即分而治之) 2.示意图 说明:可以看到这种结构很像一颗完全二叉树

The mergesort function behaves similarly, but requires that size be greater than "sizeof(void *) / 2". The contents of the array base are sorted in ascending order according to a comparison function pointed to by compar, which requires two arguments pointing to the objects being compared. ...
These two indexes ensure that the data in the tables is sorted, and uniqueness aids performance of the comparison. Query performance is improved because the query optimizer doesn't need to perform extra validation processing to locate and update duplicate rows and additional sort operations aren't ...
