Two sorts and one method to reverse an array
VBcoders
Public Sub bubbleSort(Arr(), Optional sortAscending As Boolean = True)
Dim x As Long, y As Long, vy, vx, temp
Dim lo As Long, up As Long, incr As Integer
If sortAscending Then
lo = LBound(Arr): up = UBound(Arr): incr = 1
Else
lo = UBound(Arr): up = LBound(Arr): incr = -1
End If
For y = lo To up Step incr
For x = y + incr To up Step incr
vx = Arr(x): vy = Arr(y)
If vx < vy Then
Arr(y) = vx
Arr(x) = vy
End If
Next x
Next y
End Sub
Public Sub bubbleSortText(Arr(), Optional sortAscending As Boolean = True)
Dim x As Long, y As Long, vy, vx, temp
Dim lo As Long, up As Long, incr As Integer
If sortAscending Then
lo = LBound(Arr): up = UBound(Arr): incr = 1
Else
lo = UBound(Arr): up = LBound(Arr): incr = -1
End If
For y = lo To up Step incr
For x = y + incr To up Step incr
vx = Arr(x): vy = Arr(y)
If StrComp(vx, vy, vbTextCompare) = -1 Then
Arr(y) = vx
Arr(x) = vy
End If
Next x
Next y
End Sub
Public Sub arrayReverse(Arr())
Dim tmp
Dim i As Long, j As Long, lower As Long, upper As Long, mx As Long
lower = LBound(Arr)
upper = UBound(Arr)
If (upper <> lower) Then
If (upper Mod 2 = 0) Then mx = upper / 2 - 1 Else mx = upper \ 2
For i = lower To mx
j = upper - i
tmp = Arr(j)
Arr(j) = Arr(i)
Arr(i) = tmp
Next
End If
End Sub
