Sorting Algorithm

This is a sorting algorithm.   It may be applied to a set of data in order to sort it.    
For comparing various sorts, see compare sorts.  
For other sorting algorithms,   see sorting algorithms,   or:

Task

Sort an integer array with the   radix sort algorithm.

The primary purpose is to complete the characterization of sort algorithms task.




Sub RadixSort (Old() As Int)
	Dim i, j As Int
	Dim tmp(Old.Length) As Int
	For shift = 31 To 0 Step - 1
		j = 0
		For i = 0 To Old.Length - 1
			Dim move As Boolean = Bit.ShiftLeft(Old(i), shift) >= 0
			If (shift = 0 And move = False) Or (shift <> 0 And move) Then
				Old(i - j) = Old(i)
			Else
				tmp(j) = Old(i)
				j = j + 1
			End If
		Next
		Bit.ArrayCopy(tmp, 0, Old, Old.Length - j, j)
	Next
End Sub
 
Sub Test
	Dim arr() As Int = Array As Int(34, 23, 54, -123, 543, 123)
	RadixSort(arr)
	For Each i As Int In arr
		Log(i)
	Next
