Write a method called product_odd which takes as its input an array of integers and returns the product of all the odd integers in the array. Remember that technically 0 is an even integer. For example: product_odd([1,2,3]) # returns 3, because 2 is even product_odd([0,-1,-10]) # returns -1, because 0 and -10 are even product_odd([1,2,3,4,5]) # …

returns the product of all the odd integers in an array

def product_odd(x)
  odd = x.select {|y| y%2 == 1}
  p = 1
  odd.each do |y|
    p = p * y
  end
  p
end
