In this problem set, there are some problems with the hard copy:
- the shape of the diamond doesn't appear the way it is on the web, esp. the top and the bottom (solved by changing $PAR to $BR and using $SPACE)
- unnecessary text: ¡FONT FACE=courier¿ ....... ¡/font¿ (deleted)
- no braces with hard copy (when changing them to $LBRACE and $RBRACE, the hard copy will appear correctly, but on the web we will see \lbrace and \rbrace... ???)

Ch1Projects: Problem 1
-  In Class Diamond, main method, the space(s) before the star(s) do(es) not appear correctly, both on the web and hard copy. (solved)
- There should be 3 spaces before * for answer 1, and 2 for answer 2 ($SPACE added)
- Even if the exercise requires three spaces, student can just enter a blank space before * 
since HTML counts many spaces as one. If use $SPACE, it will become & nbsp; ???
