You are asked to design an algorithm to solve the following problem:

"A program needs to determines the average of 4 integer numbers input by the user. It then displays one of the following messages fail, pass or excellent if the calculated average value is less than 40, in the range 40 - 69 or at least 70, respectively. The program also then displays the calculated average value. Note: You can assume that only valid values are input by users."

Write your algorithm using only pseudo code; apply indentation as appropriate.
