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

class Array
def step(interval, &block)
    ((interval -1)...self.length).step(interval) do |value|
        block.call(self[value])
    end
end
end

You could add the method to the class Array
