Create a string variable equal to any text value. Create another string variable whose value is the original variable concatenated with another string literal. To illustrate the operation, show the content of the variables.

Let's start with the solution:

(def a-str "abcd")
(println (str a-str "efgh"))

(def a-new-str (str a-str "efgh"))
(println a-new-str)
