==== Background ====
The permutations of a list of numbers is the list of all possible sequences of those numbers. We will represent the permutations o
(e.g., ''my-sum'').
<code>
fun my-product(lst :: List<Number>) -> Number:
doc: ```returns the product of the numbers in list lst```
cases (List) lst:
| empty => 1
| link(f, r) => f * my-product(r)
end
where:
my-product(empty) is ...
my-product([list: 2, 3]) is ...
my-product([list: 5, 2, 3]) is .
(e.g., ''my-sum'').
