Then merge sort algorithm can be applied to sort the elements, and in an entire program, only the merge sort function can be used for any other working. Example of Merge Sort in C Given below is the example of Merge Sort in C: This program demonstrates the implementation of a merge sort...

【例1.7】 有以下递归算法:void mergesort(int a[], int i, int j){int mid;if (i!=j)(mid=(i+j)/2:mergesort(a, i, mid);mergesort( a. mid+1, j) ;merge( a. i, j, mid);}其中,mergesort()用于数组a[0..n-1](设 n=2^k ,这里的k为正整数)的二路归并排序,调用该算法的...
In merge sort we follow just 3 simple steps to sort an array:Divide the array into two parts Recursively sort both the parts Then, merge those two stored parts into oneMerge sort algorithm Implementation using C++The below is the implementation of merge sort using C++ program:...
Unstable sort in ascending order: name : D B C A score: 70 70 75 80 其中稳定排序可以保证B始终在D之前;而非稳定排序,则无法保证。 1)数组的归并排序 归并排序的思想实际上是一种分治法,即将待排序数据分成两部分,分别对两部分排序,然后将这两部分合并。下面以非降序排序为例: ...

答:设mergesort(a,0,n-1)的执行次数为T(n),分析得到以下递归关系:O(n)为merge()所需的时间,设为cn(c为常量)。因此:由于趋近于1,则k=log2n。所以上机实验题1实验题1设计一个程序expl-1.cpp,输出所有小于等于n(n为一个大于2的正整数)的素数。要求:(1)每行输出10个素数;(2)尽可能采用较优的算法...
