Ruby compare if the elements of array are one of these characters
===

g = [["xx", "A"],­ ["xx", "B"]]­
g.any?{­|x,y| y.eq­l? ("A"|­|"B"||"C"­)}

I want to evaluate if the 2nd element in the sub-array is one of "A"or"B"or"C". In the above case it should return true. And return false, example, if g=[["xx","K"]["xx","B"].
