Ruby: Multiply all elements of an array

Question

Let\'s say I have an array A = [1, 2, 3, 4, 5]

how can I multiply all elements with ruby and get the result? 1*2*3*4*5 = 120

and what if there is an element 0 ?

Answer 1

Well, this is a dummy way but it works :)

A = [1, 2, 3, 4, 5]
result = 1
A.each do |i|
    if i!= 0
        result = result*i
    else
        result
    end
end
puts result
