按钮Command1，则在文本框Text2中显示该金额的大写，程序运行界面如下图所示:

i = 1: j = 10: n = 0: flag = True

Key = Val(Text1.Text)

Do While i <= jAnd flag = True

    m = (i + j) \ 2

    If a(m) = Key Then

        flag = False

    ElseIf a(m) < Key Then

        i = m + 1

        n = n - 1

    Else

        j = m– 1

        n = n + 1

    End If

Loop

数组元素a(1)到a(10)的值依次是“5,16,22,28,35,43,52,67,78,89”，变量n的值最终是0，则文本框Text1输入的数值范围可能是（   ）

Dim a(1 To 6)As Integer

Dim i As Integer,j As Integer,Key As Integer,m As Integer

a(1)=11:a(2)=22:a(3)=33: a(4)=44:a(5)=55:a(6)=66

i=1:j=6:p=0:Key=23

Do While i<=j

p=p+1

  m=(i+j)\2

  If j Mod 2=0 Then m=m+1

  If a(m)=Key Then Exit Do

  If Key<a(m) Then j=m-1

Else i=m+1

Loop

import random

a = [1,3,4,6,6,6,9,9,11,12]

key = random.randint(2,5) * 2

i,j = 0,9

while i <= j :

    m = (i + j) // 2

    if key < a[m]:

        j = m - 1

    else:

        i = m + 1

print(j)

执行该程序段后，输出的结果不可能是（   ）
