Abstract

Various methods for sorting integer numbers have been devised ranging from  bubble sort, merge sort, insertion and their likes. The complexities, f(n) of these  sorting algorithms do not make their implementation easy. In this paper, we  propose a new sorting algorithm that accepts numbers to be sorted; declare an  array for these elements, store these numbers as index of the array and copy  them out from the array the way they have been stored. This has shown that  integer numbers have naturally been sorted in their order of magnitude and that  the running time for this algorithm is linear, that is O(n). This makes it naturally  better than most known sorting schemes.
