You should send email to email@example.com which contains a single attachment containing the MIPS program. The subject line of the message should be "Assignment 3". It will be easier for me if the attachment file name is yourname.asm.
Reminder: MIPS uses byte addressing, so the addresses of successive words differ by 4, not 1.
This assignment is due March 25th, and is worth 5 points towards your final grade. There is a penalty of 1/2 point for each school day the assignment is late.
