Quick Sort Algorithm Function/Pseudo CodequickSort(array<T>& a) { quickSort(a, 0, a.length); quickSort(array<T> & a, int i, int n) { if (n <= 1) return; T pi = a[i + rand() % n]; int p = i - 1, j = i, q = i + n; while (j < q) { int comp = ...
Here, we will be implementing quicksort in C by taking the first/low element as the pivot element. We will ask the user to select the array’s length and then the values of the elements in the array. Next, we will use the partition() function and define the first element as the piv...

recursivesortfunction that calls thepartitionVecfunction each time it’s invoked. The partitioning process can be done in linear time by swapping elements in the same vector object. The latter operation is implemented using thepartitionVecfunction, which also acts as the sorting function in a ...
The Quicksort in C is the fastest known sort algorithm because of its highly optimized partitioning of an array of data into smaller arrays.
