+ACADEMIC HONESTY STATEMENT
+================================================================================
+I certify the following:
+
+1. All files hosted in this repository at any time, including any written
+material and code, are entirely of my own work. The only exception permitted to
+this rule is if the Professor(s) give explicit, written permission, in the
+assignment handout, on the webpage/PIAZZA, or in E-mail, to use or adapt other
+source code into my work. In this case, the origins of all such code is clearly
+cited in my files.
+
+2. I have not shared, transmitted, or received source code written for this
+class (including in any semester) from anyone else except the Professor(s) and
+the TAs. This includes both electronic forms (E-mail or downloading), as well as
+written or printed source code.
+
+3. Except in the case of explicit written permission given by the Professor(s),
+I have not included in my repository any source code obtained from a textbook,
+downloaded from the Internet, extracted from a software package or source code
+library, or from any other similar source.
+
+I understand that the appearance of extremely similar code fragments in more
+than one homework submission will be treated as evidence that code has been
+shared and an academic dishonesty case will be filed against me.
+
+I understand that code fragments can be extremely similar even if they are
+formatted differently and use different identifiers/labels/variables. The
+appearance of extremely similar code fragments that differ in this way will be
+regarded as evidence of an attempt to conceal that sharing has taken place.
+
+When in doubt about whether or not I am permitted to use particular source
+materials, I will obtain written permission from the Professor(s), in advance of
+my submission. Such permission is best requested and obtained by E-mail to
+cse320@cs.stonybrook.edu
