下列VB程序功能可以找出1000以内的完全数,并在标签中一一列出来。
Private Sub Command1_Click()
Dim i As Integer, m As Integer, n As Integer
Label1.Caption = "1000以内的完全数如下:"
For i = 1 To 1000
n = 0
For m = 1 To i \ 2
If i Mod m = 0 Then n = n + m
Next
If n = i Then Label2.Caption = Label2.Caption & "" & Str(i)
Next i
End Sub
该过程采用的算法是( )
