This is not a new sorting algorithm, but an idea when we need to avoid swapping of large objects or need to access elements of a large array in both original and sorted orders.

A common sorting task is to sort elements of an array using a sorting algorithm like Quick Sort, Bubble Sort.. etc, but there may be times when we need to keep the actual array in tact and use a “tagged” array to store the correct positioning of the array when it is sorted. When we want to access elements in sorted way, we can use this “tagged” array.
