The grader recently sent a message to a subset of the students in class asking for your help in finalizing the grading of homework 4. In particular, he will need your help clarifying problems with your code, helping him to get your code compiled on his system, getting the input files required by your system, or meeting with you to view your system running on your own machine. Please respond to his message as soon as possible, so we can wrap up the grading of homework 4 and move on to grading homework 5. Thank you.
