有如下 V B 程序段：Dim s(1 To 6) As String
Text1.Text = ""
For i = 1 To 5
For j = i + 1 To 6
If s(i) + s(j) < s(j) + s(i) Then
t = s(j): s(j) = s(i): s(i) = t
End If
Next j
Next i
For i = 1 To 6
Text1.Text = Text1.Text + s(i)
Next i
如果程序运行，一开始当数组元素s(1)到s(6)的值依次为“4”、“343”、“312”、“12”、“246”、“121”，运行该段代码后，文本框Text1中显示的内容为（ ）
