a(1) = 13: a(2) = 22: a(3) = 36: a(4) = 42: a(5) = 50: a(6) = 58: a(7) = 62: a(8) = 70
i = 1: j = 8: count = 0
Randomize
key = Int(Rnd * 100 )
Do While i <= j
m = (i + j + 1) \ 2
If a(m) >= key Then
count = count * 2 + 1
j = m - 1
Else
count = count * 2
i = m + 1
End If
Loop
执行该程序段后，count的值不可能的是（ ）
