At the end of the merge function, the subarray A[p..r] is sorted. Merge Sort Code in Python, Java, and C/C++ Python Java C C++ # MergeSort in Python def mergeSort(array): if len(array) > 1: # r is the point where the array is divided into two subarrays r = len(array)/...

排序算法之归并排序(Merge Sort) 基本思想 归并(Merge)排序法是将两个(或两个以上)有序表合并成一个新的有序表,即把待排序序列分为若干个子序列,每个子序列是有序的。然后再把有序子序列合并为整体有序序列。 代码实现 #include<iostream>usingnamespacestd;voidMergeArray(intArray[],intFirst,intMiddle,int...
It's truer today than it was four years ago, and more true for Java developers than it was for C. Most performance tuning reminds me of the old joke about the guy who's looking for his keys in the kitchen even though he lost them in the street, because the light's better in the...
