If you continue to have trouble with access the AKW building or room 300, please let me know! |
| 9/10/07 | Clarification of the homework: for the procedures you are asked to write, the legal inputs are specified in the problem. Your procedure *DOES NOT* have to cope gracefully with other inputs. Thus, if the problem says the input is a positive integer, then your program *NEED NOT* deal with being called on zero, or negative integers, or boolean values, or lists, and so on. |
