Problem 2873. feeling VERY lucky?
Just like Matthew's problem 2793 and Edward's problem 2872 (guess the number that Cody is thinking) but now you must solve it in your first try.
despite appearances this problem does not require any hacking at all (nor even manipulation of random streams). Look at the testsuite for details and only submit your solution if you are confident that it will pass (you do have only one chance)
