在《algorithm》中,作者单独讲mergesort作为一个小节,可以看出它的重要程度。 首先来看一下归并排序的运用场景是怎样的:将两个已排序列进行排列。 主要的思想便是:比较a[i]和b[j]的大小,若a[i]≤b[j],则将第一个有序表中的元素a[i]复制到r[k]中,并令i和k分别加上1;
Merge sort is based on Divide and conquer method. It takes the list to be sorted and divide it in half to create two unsorted lists. The two unsorted lists are then sorted and merged to get a sorted list. The two unsorted lists are sorted by continually calling the merge-sort algorithm;...

现在我们应该学习合并排序的一些编程方面。 算法(Algorithm) 合并排序继续将列表分成相等的一半,直到它不再被分割。 根据定义,如果列表中只有一个元素,则对其进行排序。 然后,合并排序组合较小的排序列表,同时保持新列表的排序。 Step 1 − if it is only one element in the list it is already sorted, return...
Merge_Sort(array, start, i); Merge_Sort(array, i+1, end); Merge1(array, start, i, end); } } 对外的接口:Merge_Sort(array, start, end); 即:传入一个数组,和起始位置中止位置,比如数组array[10],那么就是Merge_Sort(arrry,0,9)

Merge sort is a divide-and-conquer algorithm based on the idea of breaking down a list into several sub-lists until each sublist consists of a single element and merging those sublists in a manner that results into a sorted list.

The algorithm is revisited in this paper. It is discovered that sorting both operand relations externally is not necessary in the algorithm. The cost of the algorithm would be reduced greatly if only one operand relation is sorted externally. In order to overcome the shortcomings of the Sort-...
