-//(1) Complete the collatz function below. It should
-//    recursively calculate the number of steps needed 
-//    until the collatz series reaches the number 1.
-//    If needed, you can use an auxiliary function that
-//    performs the recursion. The function should expect
-//    arguments in the range of 1 to 1 Million.
-
-//def collatz(n: Long) : Long = ...

-
-//(2)  Complete the collatz-bound function below. It should
-//     calculate how many steps are needed for each number 
-//     from 1 up to a bound and then calculate the maximum number of
-//     steps and the corresponding number that needs that many 
-//     steps. Again, you should expect bounds in the range of 1
-//     up to 1 Million. The first component of the pair is
-//     the maximum number of steps and the second is the 
-//     corresponding number.

-//def collatz_max(bnd: Long) : (Long, Long) = ...
