将两个相邻&单调性相反的单调序列看作一个双调序列, 每次将这两个单调序列merge生成一个新的双调序列, 然后进行双调排序,不断上述过程。流程如下: 对于无序数组 A,相邻的两个数肯定是双调序列,比如 (a0,a1), (a2,a3) 等 步长为 2:(a0,a1) 传入bitonic sort,变成升序序列;(a2,a3) 传入 bitonic sort,变...
运行merge_sort后,我们利用c_numbers数组进行排序,我已经把下面的代码加到我的functions.py文件中了。 #Python Merge Sort from random import shuffle, sample #Generate 9999 random numbers between 0 and 100000 numbers = sample(range(100000), 9999) shuffle(numbers) c_numbers = (c_int * len(numbers))...

相信 Spark 大家都知道,它是一款基于内存的并行计算框架,在业界占有举足轻重的地位,是很多大数据公司的首选。之前介绍 Hadoop 的时候说过,相比 Spark,MapReduce 是非常鸡肋的,无论是简洁度还是性能,都远远落后于 Spark。此外,Spark 还支持使用多种语言进行编程,比如 Python、R、Java、Scala 等等。而笔者本人是专攻 ...
8. Merge Sort Write a Python program to sort a list of elements using the merge sort algorithm. Note: According to Wikipedia "Merge sort (also commonly spelled mergesort) is an O(n log n) comparison-based sorting algorithm. Most implementations produce a stable sort, which means that the ...
