sort(numArray,middle,end); merge(numArray,begin,middle,end); } } } c++动态数组分配很方便,“int* temp=new int[length]; ”length在程序运行过程中确定。为了养成良好的习惯,请在定义的指针空间使用完后,将其删除。 下面是本算法的测试代码MergeSort.cpp: #include "stdafx.h" #include <iostream> #i...
It might also be interesting to try [`std::get_temporary_buffer`](http://en.cppreference.com/w/cpp/memory/get_temporary_buffer) instead of `std::vector`. Stability While merging, you should use the left element first even if it's equivalent to the right: if (l[i] < ri[j]) ...
void merge_sort(int l, int r) { if (l < r) { int mid = (l + r) >> 1; merge_sort(l, mid); merge_sort(mid + 1, r); merge(l, mid - l + 1, mid + 1, r - mid); } } int main() { scanf("%d", &n); for (int i = 0; i < n; i++) { scanf("%d", ...
[算法]——归并排序(Merge Sort) 归并排序(Merge Sort)与快速排序思想类似:将待排序数据分成两部分,继续将两个子部分进行递归的归并排序;然后将已经有序的两个子部分进行合并,最终完成排序。其时间复杂度与快速排序均为O(nlogn),但是归并排序除了递归调用间接使用了辅助空间栈,还需要额外的O(n)空间进行临时存储。
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)
