Add this line to your application's Gemfile:
gem 'just_all_the_same'And then execute:
$ bundle
Or install it yourself as:
$ gem install just_all_the_same
require 'just_all_the_same'

# return same ary.all?(nil) but quickly
# methods
# all_same?(Immidiate Value)
# Immidiate Vale -> Integer(1,2,3...), Symbol(:str), true, false, nil
# all_nil?
# all_true?
# all_false?- A long size array.
ary = [nil]*10000- Check first item is nil? in Clang.
return false unless ary[0].nil?- Split array to half and half.
IMPORTANT!
forward_ary = ary[0...ary.size/2]

return false unless ary.size.odd? && ary[-1].nil?- Check same forward_ary and backward_ary with C function 'memcmp'.
IMPORTANT!!!
return false if memcmp(forward_ary.ptr, backward_ary.ptr, forward_ary.size)- Split forward_ary to half and half.
ary = forward_ary
forward_ary = ary[0...ary.size/2]
