If you jumped/returned to the 87 byte inside the LEA (instead of the LEA opcode itself), then yes 3 NOPs and then a c3 ret would have the same effect as 2 NOPs and then a c3 ret. A ret instruction unconditionally overwrites RIP, so it doesn't matter what the program counter was before. answered Oct 28, 2021 at 21:02.If the number was above 11 that would mean we overshoot the target, so the number must be more than 7 and less than 11. Third guess is thus (8 + 10) / 2 = 9 which brings the sum to 27 with 10 more to go and just a single guess, so that means the number is 10. TL;DR: the correct input should be 10 and 37.
