Problem H. Hasty Haul
*****
For compatibility with the Codeforces platform, your solution runs in interactive mode against a jury program. A poorly implemented interaction may result in Idleness limit exceeded or Runtime Error instead of Wrong Answer.

To handle input and output correctly, do not attempt to read extra data from the input. After finishing your output for each test case, don't forget to print a newline character and flush your output.
