Hi, I have written a program to implement Quick sort.But the program is going into an infinite loop.In the Quicks function,the while loops for incrementing and decrementing i and j are the problem.Can anybody tell me what is wrong with this Implementation of QUick Sort. sorting quicksort ...
Your main quicksort function was OK, though it got decorated with (lots of) printing too: voidquicksort(intarr[],intstart,intend){if(start < end) {dump_data("QS Pre-partition", arr, start, end);intboundary =partition(arr, start, end);printf("QS Partition: %d:%d:%d\n", start, b...
Lastly, I realize that you're most probably aware of this and this is just a learning exercise, but just in case: In most real-world applications, quick sort or merge sort are usually preferable to insertion sort, having much better performance characteristics than insertion sort in the ...
Quick Sort: Random Pivot Merge Sort: I usedstd::inplace_mergeinstead of writing my own merge function. Binary Insertion Sort: I usestd::upper_boundinstead of writing own binary search function Credit You are free to use my code to do whatever you want unless you want to use it for your...
1. Divide the data elements into two sections with equal number of elements. 2. Sort the two sections separately. 3. Merge the two sorted sections into a single sorted collection. Obviously, this is a recursive idea, where a problem is divided into smaller problems. And the division will ...

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...

Quick sort implementation: C# Copy class QuickSort { public static void Sort(int[] arr, int left, int right) { if (left < right) { int pivot = Partition(arr, left, right); Sort(arr, left, pivot - 1); Sort(arr, pivot + 1, right); } } private static int Partition(int[] ar...
