Working on a binary bomb lab. I'm new to assembly language, so I'm having some trouble understanding. I diffused phase 1 and I'm now on phase 2. I understand that the answer is 6 numbers in the format: a b c d e f. I think the first number is 0 because the first compare statement compares (%rsp) to 0x0. I don't understand what to do next.

Here's what read_six_numbers does
