Looping through an array with step

Question

I want to look at every n-th elements in an array. In C++, I\'d do this:

for(int x = 0; x

        

Answer 1

We can iterate while skipping over a range of numbers on every iteration e.g.:

1.step(10, 2) { |i| print "#{i} "}

So something like:

array.step(n) do |element|
  # process element
end
