The pairings use two elliptic curves: G1 and G2. For each of Bob's guesses, Alice tells Bob if his guess is greater than, lesser than, or equal to x. . Bob can remove either prime from the set, and then Alice can remove the remaining prime. Alice input. Alice and Bob each created one problem for HackerRank. We define the rating for Alice's challenge to be the . When Bob has selected his number, Alice will guess it. Below are the possible results: The players alternate turns. In this simple equation, Alice's Guess X will always be the inverse of Bob's number, and when added to Alice's guess will equal Bob's number. Copy.

y/n > n Alice Public Key b = 526 . The rain was still falling and Alice and Bob were terribly bored of having to stay inside the caravan, so they decided to play a game. They take moves in turn with Alice beginning. The game is that Alice chooses a number x in the interval [1,n] (where Bob knows n), and Bob tries to guess x. Explanation : Alice can select 2 and remove it that make XOR of array equals to zero also if Alice choose 3 to remove than Bob can choose any of 2/3 and finally Alice have to make his steps.
First, they get a set of n distinct integers. Figure 3. The game to play is a well known number guessing game. (1<= N <=108) Output Specification: Your function should return the maximum number of attempts required to find the number M (1<= M <=N).

It is not known whether the random process that selects a number in the machine is based on uniform . codechef-april. The game is very simple, Alice says out an integer and Bob has to say whether the number is prime or not. See more .

Think a Number Bob and Alice play a game in which Bob gives Alice a challenge to think of any number M between 1 to N. Bob then tells Alice a number X. Alice has to confirm whether X is greater or smaller than number M or equal to number M. This continues till Bob finds the number correctly. Looking at it, the greatest common divisor of these numbers is actually a, then k=max/gcd, which is the maximum number that can be accommodated in the set, then kn is what we can still put If the number of numbers that go in is odd, then the first person wins, otherwise the second person wins. He decided to take a peek into this unusual world of secret messages. $\endgroup$ - dhy. The player with the highest sum wins. So A sends to B a random number X. They would assign all of the characters a sequential number as well. The name is not "Bob". Alice tells him she pressed the button 8 times and it always said 'yes'. Correct and detailed answer will be Upvoted else downvoted.

And Alice thinks any one of the numbers from 1 to 108. Compare the Triplets Hackerrank Solution.

Program should read from standard input and write to standard output.After you submit a solution you can see your results by clicking on the [My Submissions] tab on the problem page. If it is impossible to remove any elements, the current player loses the game. Bob doesn't think she has learnt it properly and hence he has decided to quiz her. B then forms Y by encrypting X under key K and sends Y back to A" Because this sort of thing is quite hard to follow, theorists stopped using the unadorned letters A and B to represent the main players and started calling them Alice and Bob.

I won't tell the code as so many people here have already done without explaining anything. Apr 10, 2012 at 10:23pm. In a game that Bob and Alice play, Bob challenges Alice to come up with any number M between 1 and N. Then Bob gives Alice the number X. Alice then generates a temporary symmetric key (the pair of orange keys) and uses Bob's public key (red padlock) to securely send it to Bob. Alice cannot make 8 out of the numbers on the table. Hence, we get ( A = 2, B = 2). Your task is to find the maximum number of attempts Bob needs to guess the number thought of by Alice.
