Augment the starting program to total the value of all the elements in
the list as well as calculate their average. After this the program will
output the total and average.
Modify the solution from Problem #2 so it only totals the numbers which
are positive. Similarly the average should only be based on the numbers
which are positive (and not every number in the list)

Problem 2] [Solution - don't look at this until you have given the problem a
real try!]
