In general, make sure that you don't confuse references and objects. vals are immutable references (constant pointers in C). That is, when you use val x = new MutableFoo(), you...
Is log(n!) = Θ(n·log(n))?
...og(n - 1) + log(n) (larger half of the terms of log(n!)). Actually, I just read the question and saw that the clue is stated in the question. Basically, (n/2)^(n/2) <= n! <= n^n => log((n/2)^(n/2))<=log(n!)<=log(n^n) => Θ(n/2 * log(n/2))<=log(n!)<=Θ(n*log(n))
