How do I modify the second element in a nested array, within an array, alone? - Ruby

Question

So say I have a 2D array like this:

list = [["auburn", "http://auburn.craigslist.org"], ["birmingham", "http://bham.craigslist.org"], ["dothan", "http://dothan.craigslist.org"]]

I would like it to look like this:

list = [["auburn", "http://auburn.craigslist.org/web/"], ["birmingham", "http://bham.craigslist.org/web/"], ["dothan", "http://dothan.craigslist.org/web/"]]

So I have just modified the second element within each nested array.

How do I do that in Ruby?

Thanks.

Answer 1

list.map! { |elem| [elem[0], elem[1] << '/web/'] }

Answer 2

Try this

list.map!{|f,l| [f, l + "/web/"]}
