Name Squash

Take your name and the name of another student in the group and create a combined name

A collection of two people

Create a collection containing your full name and the name of another person (or two imaginary people if you prefer)

Give your collection a name so you can use it in later exercises on this page.

(def students ["Ada Lovelace" "Anne-Marie Imafidon"])

Split first and last names

Assuming there is a first and last name for each person we need to split them into individual strings first.

Write a function call to split each name in your students collection

()

(clojure.string/split students #" ")
;;
;; => ["Ada" "Lovelace" "Anne-Marie" "Imafidon"]

In JavaScript the above gives a rather messy output of nested collections.

Mapping over the student collection gives cleaner return value

(map #(clojure.string/split % #" ") students)

We can also flatten the result to make it look nicer

(flatten (map #(clojure.string/split % #" ") students))

Hint

clojure.string/split function will split a string on a given pattern (regular expression), such as a space: #" ".


Name splitting function

Write a function called name-split that a full name as a string and return two seperate strings, one for the first name and one for the last name.

(defn name-split
  "Splits a name into first & last names"
  [name]
  (clojure.string/split name #" "))
;;
;; (name-split "Ada Lovelace")
;; =>["Ada" "Lovelace"]

Jumble the names

Write a function to jumble up the first and last names to create a new person

For example, take the first name from the first person and join it with the last name from the second person

()

(defn jumble-names [names]
  (let [first-person (first names)
        second-person (second names)
        first-person-first-name (first (name-split first-person))
        second-person-second-name (second (name-split second-person))]
    (str "Hello " first-person-first-name second-person-second-name)))
;;
(jumble-names students)
;; => "Hello AdaImafidon"

Hint

Remember, the let function defines local names that you can use for temporary values. Using several names with the let function can make this challenge a little simpler to solve
