        Part 1:

        • Write a while and a for loop to calculate the product of the first 10 integer numbers

        starting at 1.

        • Write a while and a for loop to calculate the product of the first 20 integer numbers

        starting at 1.

        • After each loop print the parameters of the loop: starting number, ending number, and

        the result (product).

        • Part 2:

        • For the “Gauss” among you: Given m=1777 and n=2022, what is the sum of the numbers

        between m and n (both included in the sum)?

        • As a brain teaser (not required to solve), see slide #12 to find inspiration to derive a

        formula for this problem.
