This question already has an answer here:

Check if a value exists in an array in Ruby 23 answers

Ruby's #include? method can be used here:

arr = [[1, 2], [3, 4], [4, 5]]
arr.include?([1, 2])
# => true

Hope this helps!

Just use bigarray.include? smallarray bigarray.include? smallarray . It's the same way you'd check for membership with any other list. Example
