VBS的快速排序

下面是VBS的快速排序代码，适合数字和字符串数组：

Public Function QSort(ByRef ReArr, ByVal head,ByVall tail)
ReArr是待排序数组，head和tail是该数组的最小下标和最大下标
Dim lef,rig
Dim pivot

If head<tail,Then
lef=head
rig=tail
pivot=ReArr(lef)
While (lef<>rig)

While (lef<rig and ReArr(rig)>=pivot)
rig=rig-1
Wend
If lef<rig Then
ReArr(lef)=ReArr(rig)
lef=lef+1
End If

While (lef<rig and ReArr(lef)<=pivot)
 lef=lef+1
Wend

If lef<rig Then
ReArr(rig)=ReArr(lef)
 rig=rig-1
End If
Wend

ReArr(lef)=pivot
call QSort(ReArr,head,lef-1)
call QSort(ReArr,lef+1,tail)

End If
End Function
