Quick Sort C Code Implement void QuickSort(int* pData,int left,int right){ int i = left, j = right; int middle = pData[(left+right)/2]; // midlle value int iTemp; do { while (pData[i] < middle && i < right) i++; ...
Array entry a[r] becomes the pivot element x. Lightly shaded array elements are all in the first partition with values no greater than x. Heavily shaded elements are in the second partition with values greater than x.We compared the array entry a[j] and element x, if it is greater than...

Quicksort is one of the fastest general-purpose sorting algorithms used in contemporary code bases. It utilizes the divide-and-conquer technique similar to the merge sort algorithm. Although, the former one depends on an operation commonly called partitioning. The original vector is split on the ...
