1. (2020高三下·金华月考) 有VB程序段如下：

Dima( 1 To 5) As Integer

Dimi As Integer, j As Integer, s As String

s=“”

    For i= 2 To 5

        For j=i To 5

            If j Mod i=0 Then a(j) =a(j)+1

        Next j

    Next i

    For i= 1 To 5

        If a(i) <>1Then s=Str(i) +s

    Next i

    Text 1．Text=S

若数组a的初始值都为0，则运行该程序段后，Text 1中显示的内容为（  ）
