Testing the Solution:
$ mkdir a b c d e
$ touch a/1 b/2 c/3 d/4 e/5 e/a e/b
$ find . -type f ! -path "./a/*" ! -path "./b/*"
./d/4
./c/3
./e/a
./e/b
./e/5
You were pretty close, the -name option only considers the basename, where as -path considers the entire path =)

Scala: what is the best way to append an element to an Array?
...can use :+ to append element to array and +: to prepend it:
0 +: array :+ 4
should produce:
res3: Array[Int] = Array(0, 1, 2, 3, 4)
It's the same as with any other implementation of Seq.
