asp怎么实现两个数组的比较,如果数组字符相同则过滤，不相同则把数组记录返回

asp如何实现两个数组的比较,如果数组字符相同则过滤，不相同则把数组记录返回?
比如:
数组一:
a(0)   =   "aaa "
a(1)   =   "bbb "
a(2)   =   "ccc "

数组二:
b(0)   =   "aaa "
b(1)   =   "lll "
b(2)   =   "ccc "

怎么些循环使这两个数组记录一一做比较呢,也就如下:
a(0)   =   b(0)
a(1)   =   b(1)
a(2)   =   b(2)

如果字符不相等,则返回该变量，把不相同的变量放到新的一个数组c()中


------解决方案--------------------
Dim a(2), b(2)
a(0) = "aaa "
a(1) = "bbb "
a(2) = "ccc "

b(0) = "aaa "
b(1) = "lll "
b(2) = "ccc "

Set dic = CreateObject( "Scripting.Dictionary ")

For i=0 To UBound(a)
If a(i) <> b(i) Then dic.Add a(i), b(i)
Next
c = dic.Items
d = dic.Keys
For i = 0 To UBound(c)
Response.Write c(i)
Next
