Your basic approach seems sound:
(map #(str "Happy Birthday " %) (assoc (vec (replicate 4 "To You")) 2 "Dear
XXX") -> 81 chars including white space
for(int i=0;i<4;i++){System.out.println("Happy Birthday "+(i==2?"Dear
XXX":"To You"));}) -> 88 chars
(1 to 4).map{i=>"Happy Birthday %s".format(if(i==3)"Dear XXX"else"To
You")}.foreach{println(_)} -> 95 chars
Anyone have a shorter version? :)
