Guess the Number
I am thinking of a number between $1$ and $1000$, can you guess what number it is? Given a guess, I will tell you whether the guess is too low, too high, or correct. But I will only give you $10$ guesses, so use them wisely!
Your program should output guesses for the correct number, in the form of an integer between $1$ and $1000$ on a line on its own. After making each guess, you need to make sure to flush standard out.
After each guess, there will be a response to be read from standard in. This response is a line with one of the following three words:
“lower” if the number I am thinking of is lower than your guess
“higher” if the number I am thinking of is higher than your guess
“correct” if your guess is correct
After having guessed the right answer your program should exit. If you guess incorrectly $10$ times, you won’t get any more chances and your program will be terminated.
