Question

OK so i have this hash

>  h.each do |key, value|
>     puts key
>   p         


        

Answer 1

You'll want to recurse through the hash, here's a recursive method:

def ihash(h)
  h.each_pair do |k,v|
    if v.is_a?(Hash)
      puts "key: #{k} recursing..."
      ihash(v)
    else
      # MODIFY HERE! Look for what you want to find in the hash here
      puts "key: #{k} value: #{v}"
    end
  end
end

You can Then take any hash and pass it in:

h = {
    "x" => "a",
    "y" => {
        "y1" => {
            "y2" => "final"
        },
        "yy1" => "hello"
    }
}
ihash(h)
