B"This problem is interactive. We decided to play a game with you and guess the number x ( 1 <= x < n ), where you know the number n . You can make queries like this: You win if you guess the current number with no more than 10 queries. The interaction begins by reading an integer n ( 2 < n <= 1000 ), which is written in the input data on its own line. Then you can make no more than 10 queries. To make a query, print on a separate line: Print the answer, like the queries, on a separate line. The answer doesn't count in number of queries. To output it, use the following format: After that, your program should exit. You have to use a flush operation right after printing each line. For example, in C++ you should use the function fflush(stdout), in Java -- System.out.flush(), in Pascal -- flush(output) and in Python -- sys.stdout.flush(). Note that the interactor is not responsive. To make a hack, use the following format: a single line must contain two numbers x and n , separated by a space. In the first sample initially x = 2 . After the first query x = 3 , lfloor frac{x}{n} rfloor = 1 . In the second sample also initially x = 2 . After the first query x = 3 , lfloor frac{x}{n} rfloor = 0 . After the second query x = 4 , lfloor frac{x}{n} rfloor = 0 . After the third query x=5 , lfloor frac{x}{n} rfloor = 1 . "...
