Write a method total which takes an Array of numbers as its input and returns their total (sum). For example, total([1,2,3]) # => 6 total([4.5, 0, -1]) # => 3.5 total([-100, 100]) # => 0

Calculating the array total

def total(array)
  total = 0

  array.length.times do |i|
    total = total + array[i]
  end

  total
end

puts total([1,2,3])      # => 6
puts total([4.5, 0, -1]) # => 3.5
puts total([-100, 100])  # => 0
