1. Write an algorithm (using pseudocode) that takes as input an integer n and prints out the integers from n to 1 in descending order if n is positive and prints out an error message if n is zero or negative. Draw a flowchart that represents the algorithm.

Hint: You will need both a selection and an iterative structure.

Important: Students often think they need a list to solve this problem; a list is not required. While it can be solved with a list the solution becomes overcomplicated.

Identify the different control structure elements Sequential, Conditional, Iterative in your flow chart, by using different colours or some other means be creative
