Const s1 = "AACBBB"
s2 = "": i = 1
Do While i <= Len(s1)
m = 1
Do While Mid(s1, i, 1) = Mid(s1, i + 1, 1)
i = i + 1
m = m + 1
Loop
s2 = CStr(m) + Mid(s1, i, 1) + s2
i = i + 1
Loop
Text1.Text = s2
执行该程序段后，变量s2的值是( )

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
