I’ve done almost all the levels of the game but I’m stuck in this one, how to solve this level?
# Say the correct speed to insert our spybot into the line of robots.
# We must find the exact speed in robot motor revolutions per month.
# We've found the part of the robot code that controls the speed,
# but we don't know how to interpret it to find the final speed.
# What's the value of %eax when the last instruction (the NOP) runs?
speed = 0 # ∆ Put your answer here.
hero.say(speed)
