Objective

• Define the problem by constructing an algorithm using pseudocode
• Create an IPO diagram showing input, output, and processing steps
• What control structures (sequence, selection and repetition) are required?
• What variables are required?
• Show a check of your solution with test data for at least two valid test cases

Create an algorithm to:

1. Find the sum of the elements of an array
2. Find the mean (average) of the elements of an array.
