已知数组元素a(1)到a(9)的值为19,28,37,46,55,64,73,82,91,若在Text1中输入29,然后执行下面程序段:
Key = Val(Text1.Text) \10
Text2.Text = ""
i = 1: j = 9: f = False
Do While i <= j And Not f
m = (i + j)\ 2
If a(m) Mod 10 = Key Then search = m
f = True
ElseIf a(m) Mod 10 > Key Then i = m + 1
Else
j = m - 1
End If
Text2.Text = Text2.Text + Str(m)
Loop
程序运行后,文本框Text2中显示的内容是( )
