There is a sequence of numbers of length (), with each number being either 1, 2, or 3. Can you guess this sequence?
This is an interactive problem. You should keep outputting numbers between 1 and 3, inclusive and reading a line of input after each output. The line will be
NO if your guess for the current position is incorrect or
YES if you guessed the current position correctly. If you guessed the whole sequence correctly, you will receive a single line
DONE, and you should terminate your program then.
After each time you output a number, you might need to flush the output. In Python, you can do this with
sys.stdout.flush() (after you
>>> denotes your output: don't actually print this out.
>>> 1 YES >>> 3 NO >>> 2 YES >>> 1 NO >>> 2 NO >>> 3 YES DONE
The sequence is 1, 2, 3.
There is only one input file, and the length of the sequence is exactly 15. Your score will decrease with more wrong guesses, so guess as wisely as you can given that you have no information whatsoever about the secret sequence (or... do you?).
