+//    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.

+
+//(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.
