Exercise: Name Squash

In this exercise we will write functions to split and join strings together.

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

Note::A collection of two people

Create a collection of two people. Each person should have a two part name, eg. "Ada Lovelace"

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

()

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

Note::Split first and last names

Define a function called name-split. The function should take one argument, which is a string of a persons name, first and last as one string. The behaviour of the function splits the names into two strings Then call the function with a name to split

()

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

Hint::clojure.string/split

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

Note::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 famous-scientists)
;; => "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
