I'm doing some exercises in ruby, my task was this

Write a method **first_half(array)** that takes in an array and returns a new array containing the first half of the elements in the array. If there is_ an odd number of elements_, return the first half including the middle element.

My solution was this

def first_half(array)
  new_arr = []
  i = 0
  while i < array.length / 2.0
    new_arr << array[i]

    i += 1
  end

  return new_arr

end

print first_half(["Brian", "Abby", "David", "Ommi"])# => ["Brian", "Abby"]
puts
print first_half(["a", "b", "c", "d", "e"]) # => ["a", "b", "c"]

end this works, but when I change 2.0 to 2.5 editor show only my first two elements "a" and "b". Any explanation why?
Maybe I just overthink this and this is something stupid...

I just want to hear different thoughts

thanks in advance <3
