Notice, in the above, that the check to make sure the inputs are valid are done on entry to the recursive function. This simplifies the last part of the function. The same code could, alternatively, be written similar to yours, as: void quicksort(int *arr, const int left, const int...
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 reason I don't want to use a dynamic array is that it increases the run time of the algorithm. Some notes about the implementation details: Radix Sort: Most Significant Digit, base 2. Quick Sort: Random Pivot Merge Sort: I usedstd::inplace_mergeinstead of writing my own merge funct...
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 ...

In programming, there are any numbers of sorting algorithms, some of them are given below, Bubble sort Selection sort Insertion sort Merge sort Quick sort Randomized Quick sort (an optimized quick sort) Problem with other sorting techniques Vs. Why to use merge sort?
the string can be represented as an array of characters or using string class that is supported by C++. Each string or array element is terminated by a null character. Representing strings using a character array is directly taken from the ‘C’ language as there is no string type in C. ...
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 ...
