Forum: Ruby on Rails Remove array within hash

My orginal hash is like as

==> hash = {"sku_id"=>[4], "brand_active"=>["true"],
"salesman_active"=>["true"]}

How to remove the array within hash. that means to convert the hash like

==> {"sku_id"=>4, "brand_active"=>"true", "salesman_active"=>"true"

Come on, why even ask this!? Check the doc for all essentials -- Array, 
Hash, String.

hash.each { |k,v| hash[k] = v[0] }

In addition to Aleksey's response re how to UNdo the arraying, would
it be possible simply to NOT put the data in as arrays in the first
place?
