ArrayIndex.rb

=begin

Complete the solution. It should try to retrieve the value of the array at the
index provided. If the index is out of the array's max bounds then it should
return the default value instead.

Example:

data = ['a', 'b', 'c']
solution(data, 1, 'd') # should == 'b'
solution(data, 5, 'd') # should == 'd'

# negative values work as long as they aren't out of the length bounds
solution(data, -1, 'd') # should == 'c'
solution(data, -5, 'd') # should == 'd'

=end

# My Solution
def solution(items, index, default_value)
  index.abs > items.length ? default_value : items[index]
end

# Another Solution
def solution(items, index, default_value)
  items.fetch(index, default_value)
end
