Sorting is a common operation in many applications, and efficient algorithms to perform it have been developed.
Computer manufacturers of the 1960’s estimated that more than 25 percent of the running time of their computers was spent on sorting, when all their customers were taken into account. In fact, there were many installations in which the task of sorting was responsible for more than half of the computing time. From these statistics we may conclude that either
- there are many important applications of sorting, or
- many people sort when they shouldn’t, or
- inefficient sorting algorithms have been in common use.

Quicksort is a comparison sort, meaning that it can sort items of any type for which a "less-than" relation (formally, a total order) is defined. Efficient implementations of Quicksort are not a stable sort, meaning that the relative order of equal sort items is not preserved.
/* This function takes last element as pivot, places
the pivot element at its correct position in sorted
array, and places all smaller (smaller than pivot)
to left of pivot and all greater elements to right

{
int pivot = arr[high]; // pivot
int i = (low - 1); // Index of smaller element

// If current element is smaller than or
// equal to pivot
if (arr[j] <= pivot)
{
i++; // increment index of smaller element
swap(&arr[i], &arr[j]);
}

Merge sort is an efficient, general-purpose, comparison-based sorting algorithm. Most implementations produce a stable sort, which means that the order of equal elements is the same in the input and output.
void merge(int *,int, int , int );
void merge_sort(int *arr, int low, int high)
{
int mid;
if (low < high){
//divide the array at mid and sort independently using merge sort
mid=(low+high)/2;
merge_sort(arr,low,mid);
merge_sort(arr,mid+1,high);
//merge or conquer sorted arrays
merge(arr,low,high,mid);
}
}
// Merge sort
void merge(int *arr, int low, int high, int mid)
{
int i, j, k, c[50];
i = low;
k = low;
j = mid + 1;

c[k] = arr[i];
k++;
i++;
}
else {
c[k] = arr[j];

}

Let \((\hat{\mathbf{x}},\hat{\mathbf{y}},\hat{\mathbf{z}})\) denote the spatial frame (does not rotate with the body) and \((\hat{\mathbf{x}}',\hat{\mathbf{y}}',\hat{\mathbf{z}}')\) denote the body frame.
The following two procedures of rotation are identical.
vs.
In particular, the point \((\theta,\varphi)\) on \(S^2\) may be obtained from both of the above procedures with \(\gamma = \varphi\) and \(\beta=\theta\).
This equivalence has applications in, for example, the Wigner \(D\) matrices.
