Dim i, j, m, k As Integer
i = 1: j = 8
a(1) = 87: a(2) = 66: a(3) = 59: a(4) = 40: a(5) = 39: a(6) = 30: a(7) = 22: a(8) = 13
k = Val(Text1.Text)
Do While i <= j
m = (i + j + 1) \ 2
If a(m) < k Then j = m - 1 Else i = m + 1 Loop
Text2.Text = Str(i)
程序执行完后，i 的值是 4，则 k 的值不可能是（ ）

y = sin x， x∈R， y∈[–1，1]，周期为2π，函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x， x∈[–1，1]， y∈[–π/2，π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
