    The each_with_index method in Ruby's Enumerable module iterates over a collection, passing both the element and its index to the block. It's useful when you need both the value and its position during iteration. Ekbet Registration

    First test answer: ["3:panda", "4:tiger", "5:deer"]

    def skip_animals(animals, skip)
    animals[skip..-1].each_with_index.map {|v,i| "#{i+skip}:#{v}" }
end
