The following are clarifications and further discussion on Project 3. Many of these items were generated based on questions received during lectures and in e-mails to Mr. Kukla and Ms. Mitchell. Check this page frequently to keep informed!

• Because of inconsistencies in the sample executable regarding leading and trailing whitespace, the following decision has been made. Your program does not have to check for either leading or trailing whitespace. You may assume that the user will not type in a command with either leading or trailing whitespace.
• You may assume that a command will be no longer than 100 characters.
• Your stack class does not have to be generic. That is, it may be a stack that handles only strings. (Note: Non-generic data structures will NOT be allowed on Project 4, so study your templates!)
