I'm going to assume that you're aware of qsort (C implementation of quicksort) and std::sort (C++ sorting routine). Therefore, you are doing this as a programming exercise. There's a reinventing-the-wheel tag for that if you happen to do something similar in the future. using name...
I followed Tim Roughgarden's explanations in his MOOC on algorithms. But he assumes the keys are all distinct and says that having Quicksort work efficiently on many duplicated keys is trickier than it seems and point to Robert Sedgewick and Kevin Wayne book on algorithms. I checked it and t...
The below is the implementation of merge sort using C++ program: #include <iostream>usingnamespacestd;inttemp[10000];voidmergearrays(intar[],ints,inte) {intmid=(s+e)/2;inti, j; i=s; j=mid+1;intx=s;while(i<=mid&&j<=e) {if(ar[i]<ar[j]) { temp[x++]=ar[i]; i++; ...
Quicksort is one of the most intriguing sorting alg orithms and is a part of C, C++ and Java libraries. This paper analyzes t he results of an empirical study of existing Quicksort implementations undertaken by authors. This paper formulates an alternative implementation of Quicksort. It is ...

1.2 Pimpl模式的目的和优势 (Purpose and benefits of using Pimpl) 使用Pimpl模式的主要目的是实现数据和函数的封装,以及提高编译时效率。当我们修改类的私有成员或实现时,不需要重新编译使用该类的所有代码,因为它们只依赖于类的接口,而不是实现。这可以大大减少项目的编译时间,特别是在大型项目中。
The basic idea of Quicksort algorithm can be described as these steps: 1. Select an element as a pivot element. 2. Data elements are grouped into two sections: one with elements that are in lower order than the pivot element, one with element that are in higher order than the pivot ele...
In case you are using older versions of Java that support only the raw "Comparable" interface type, here is my old implementation: /* HyArraysOld.java * This class contains sorting methods similar to java.util.Arrays.sort(). * All sorting methods should have a signature of ...

No support for using. The C plugin API does not allow to load a Stata dataset from disk. Option sort is not available. It can also check IDs with if and in conditions. Differences from gsort hashsort behaves as if mfirst was passed. To recover the default behavior of gsort pass optio...
