Step 1: We start with an unsorted array, and we know that it splits in half until the sub-arrays only consist of one element. The Merge Sort function calls itself two times, once for each half of the array. That means that the first sub-array will split into the smallest pieces ...
First, we know that a node in a segment tree stores the answer for a range of length 2x2x for some xx, but we can also store in it all the elements in the range sorted in a vector (using merge sort algo) or set or whatever. Here I am going to give a few examples how we ...

基本排序算法05---合并排序(merge sort) 合并排序的算法利用了递归、分而治之的思想。 我们假设列表的长度为偶数对其过程进行分析: 1.计算一个列表的中间位置,将其分割为两个子列表 2.重复上述操作,直至子列表的长度为1 3.将长度为1的两个子列表通过比较之后进行排序,合并成一个长度为2的列表 4.将长度为...

The parallel quicksort algo- rithm concept begins with partitioning the data in parallel. Next, the partitioned data are merged. While the data are smaller, they are sorted by any sorting algorithm independently. In 1990, a parallel quicksort algorithm on an ideal parallel random access machine...
