Dim s(1 To 81) As Integer, i As Integer, j As Integer, c As Integer, temp As Integer
c=0 : s(1) = 0
For i = 1 To 9
For j = 1 To i
temp = s(j * i)
s(j * i) = j * i
If temp <> s(j * i) And s(j * i) Mod 9 = 0 Then c = c + 1
Next j
Next i
该程序段运行后，变量 C 的值为（ ）

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
