Assign to an array and replace emerged nil values

Question

Greetings!

When assigning a value to an array as in the following, how could I replace the nils by 0?

array = [1,2,3]
array         


        

Answer 1

nil.to_i is 0, if all the numbers are integers then below should work. I think It is also the shortest answer here.

array.map!(&:to_i)
