Split an array in ruby based on some condition
Try the partition method
@arr1, @arr2 = @level1.partition { |x| x[0] > 2.1 }The condition there may need to be adjusted, since that wasn't very well specified in the question, but that should provide a good starting point.
something like this?
arr = [ ["3.1", 4], ["3.0", 7], ["2.1", 5], ["2.0", 6], ["1.9", 3]]arr1, arr2 = arr.inject([[], []]) do |f,a| a.first.to_f <= 2.1 ? f.last << a : f.first << a; fendarr = arr1 + arr2.reverse# => [["3.1", 4], ["3.0", 7], ["1.9", 3], ["2.0", 6], ["2.1", 5]]
