Why would you post the answer to a homework assignment online?
The homework from CMU 15-213 is not the same binary used in this series. I’m using the “self-study” from the CS:APP website. If I recall correctly, each CMU student taking 15-213 receives a unique binary as their homework but I have no details about what is the difference between them.
Not everyone on the internet is a CMU student so others might benefit from reading the posts and maybe learning a little bit in the process.
