#y procedure calculates the frequency of each character in the string
y = Proc.new{|x| x.chars.group_by{|i| i}.values.collect{|i| i.count}}
z = Proc.new{|m,n| y.call(m) == y.call(n)}
z.call("foo", "app")
#the one liner, less readable..:) well technically two to make it general
y = Proc.new{|m,n| m.chars.group_by{|i| i}.values.collect{|i| i.count} == n.chars.group_by{|i| i}.values.collect{|i| i.count} }
y.call("foo", "app")
