Solve 5 of the following problems
1. A function test-min that returns the lower value in a List of numbers
(test-min L)
2. A function test-average that returns the average of all values in a List of numbers
(test-average L)
3. A function test-fibonacci that prints the first n elements of the fibonacci series
(test-fibonacci n)
4. A recursive function that returns the leftmost even element in a list of numbers
(test-even L)
5. A functions that traverse a list and returns how many of its elements are 0
(test-count-zeros L)
6. A recursive function that return the N member of a list L (assuming that the
elements are numbered from zero onwards):
(test-get n L)
7. A recursive function that returns non-NIL if x is a member of the list L.
(test-is-in-list x L)
