Not exactly sure what the intended solve was, but in this challenge, sending the correct number is enough to solve the challenge. If you send a number that's too high, the service terminates, complaining about overheating. If you send a number that's too low, the service says "Not enough yet." The challenge can be solved by connecting and sending a single number each time, sending higher and lower numbers until the service spits out the flag.
