Merge Sort Algorithm - Learn about the Merge Sort algorithm, an efficient sorting technique that divides and conquers to sort data in linearithmic time. Explore its implementation and applications.
with a worst-case time complexity ofO(n log n). This means that regardless of the initial order of the elements in the array, Merge Sort will always take the same amount of time to sort an input of sizen.
1. 排序算法函数:sort 定义:对容器中的元素进行排序。语法:sort(container.begin(), container.end(), compare_function);其中compare_function 是一个可选的比较函数,用于自定义排序方式。实例 #include <algorithm> #include <vector> #include <iostream> int main() { std::vector<int> numbers = {5, 2...
}voidmergesort(inta[],intfirst,intlast,inttemp[]) {if(first <last) {intmid = (first + last) /2; mergesort(a, first, mid, temp);//左边有序mergesort(a, mid +1, last, temp);//右边有序mergearray(a, first, mid, last, temp);//再将二个有序数列合并} }boolMergeSort(inta[],i...
//5、Merge Sort 归并排序voidmerge(inta[],intleft,intmid,intright);voidmergeSort(inta[],intleft,intright)// left需要排序数组 a[] 的左端下标,right为右端下标{intlength = right - left +1;if(length <2)return;intmid = (right + left) /2;mergeSort(a,0, mid);mergeSort(a, mid +1,...
defmergeSort(arr,n):__mergeSort(arr,0,n-1)pass 这里是设置了一下如果 才需要进行,否则就不要了,因为两边都是有序的,如果中间不一样那就真不一样了。最后同上面几个来对比一下时间: 事实上还可以再快点,我们是切分到一个数据的时候直接合并的,如果我们切分到小数据之后就拿插入排序,效果可能会更好,虽...
MergeSort(myarr[], left, right) If right > left 1. Middle point is found to divide the array into 2 halves: m = (left+right)/2 2.MergeSort is called for first half: Call mergeSort(myarr, left, m) 3. MergeSort is called for second half: ...
