小学奥数题 四位数相乘（VBA代码）

小学题：四位数乘以4等于另一四位数，1至8不重复【请找出各字母不重复代表1至8，且符合条件ABCD*4=EFGH的具体四位数？】

用VBA解决

Sub test()

Dim i, j, k  As Integer
Dim i1, i2, i3, i4, j1, j2, j3, j4



k = 0

For i = 1000 To 2499
    

    i1 = Int(i / 1000)

    If i1 <> i2 And i1 <> i3 And i1 <> i4 And i2 <> i3 And i2 <> i4 And i3 <> i4 Then
                          
            j = 4 * i
            j1 = Int(j / 1000)
