Hi folks,
In an array value i need to find except first two values,
example:
[1,2,3,4,5,6,7,8 ]
in that i need to get values except [1,2].
How can i get it from this array??
please advise…
[1,2,3,4].select{|n| ![1,2].include? n}
Send from my cellphone
[1,2,3,4,5,6,7,8 ][0…1]
Look at documentation
Class: Array (Ruby 1.9.3).
Generally good advice is to bookmark this
http://ruby-doc.org/core-1.9.3/
page.

Could you not just do [1, 2, 3, 4, 5, 6, 7, 8][2…-1]
If you are using Rails,
%w( a b c d ).from(0) # => %w( a b c d )
%w( a b c d ).from(2) # => %w( c d )
%w( a b c d ).from(10) # => %w()
%w().from(0) # => %w()

And, of course, you can just you plain 'ol Ruby for this too:
a = [1,2,3,4,5]
a[2…-1] # => [3,4,5]
%w[ a b c d e ][3…-1] #=> [‘d’, ‘e’]
