An engineer reviews the algorithm shown in Figure 1 and makes the following statement:

"Currently, if the user enters 'y' or 'n' instead of 'yes' or 'no', they will sometimes get unexpected results. This design flaw could have been easily prevented."

Explain why this problem has occurred and describe what would happen if a user entered 'y' instead of 'yes' when prompted at line 2.

You may include references to line numbers in the algorithm where appropriate. You do not need to write or correct any of the pseudocode.
