(Consult the IIT Student Handbook for this code.)In particular, the work that you submit for homework and individual project assignments and your work on examination papers must be your own. You may consult with other students about homework and project assignments. In fact, discussion of the assignments is encouraged. However, the written material that is submitted must be your own. Such written material includes computer programs and the results of using computer programs (computed values, plots, etc.). If the above policy or any part of IIT's Code of Academic Honesty is violated in regard to a submitted homework assignment, a grade of zero will be assigned to the work. If the above policy or any part of IIT's Code of Academic Honesty is violated in regard to a submitted project assignment or an examination paper, a punitive failing grade will be given in the course. In both cases, the matter will be reported to the appropriate university officials and offices. In the case of a second offense (with the first offense in this or any other course), expulsion from the university will be advocated.。

Part 3 In a banking context, a debit memo is notification from the bank that it has debited the depositor's account. Since the depositor's account is a liability of the bank (a credit balance account), the debit notification means the bank has reduced the depositor's account balance. Conversely, a credit memo is a notification that the depositor's account has been credited, which means the bank has increased the depositor’s cash balance.
