用VB编程算的

Private Sub Command1_Click()

Dim a%,n%,k%,b%,i%

a = InputBox("a")

n = InputBox("n")

For i = 1 To n

If a Mod 2 0 Then

a = 3 * a + 5

Else:For k = 1 To Sqr(a)

b = a / (2 ^ k)

If b Mod 2 0 Then

a = b:Exit For

End If

Next k

End If

Next i

Print a

End Sub

我用26代进去算对的外...

那等你们老师报答案后告诉我一下..
