This blog post got me thinking.

Basically it contains both a Java one liner and Scala one liner.
Java:
for(int i=0; i<4; i++) { System.out.println("Happy Birthday " + (i==2
? "Dear XXX" : "To You")); }
Scala:
(1 to 4).map { i => "Happy Birthday %s".format(if (i == 3) "Dear XXX"
else "To You") }.foreach { println(_) }
the goal is to generate
Happy Birthday To You
Happy Birthday To You
Happy Birthday Dear XXX
Happy Birthday To You
I started thinking about how to do this in clojure. My first reaction was to
think of the sentences as two sequences. Uses replicate to generate
them, and map str to join them from two collections.
ie, (map str (replicate 4 "Happy Birthday ")...
Is there a more "clojure" way to do it?
because using replicate to generate the 2nd sequence seem like cheating.
ie, replicate 2 "To You", 1 "Dear XXX", and then "To You" again.
