In the previous challenge, we learned about each
method being central to all
of the methods provided by Enumerable
class. One of such useful methods is
each_with_index
which allows you to iterate over items along with an index
keeping count of the item.
For example,
> colors = ['red', 'green', 'blue']
> colors.each_with_index { |item, index| p "#{index}:#{item}" }
"0:red"
"1:green"
"2:blue"
As you can note, the counting of items starts from 0.
In this challenge, your task is to complete the skip_animals
method that
takes an animals
array and a skip
integer and returns an array of all elements except first skip
number of items as shown in the example below.
For example,
> skip_animals(['leopard', 'bear', 'fox', 'wolf'], 2)
=> ["2:fox", "3:wolf"]
It is guaranteed that number of items in animals
array is greater than the
value of skip
.
