@@pieluver1234 Its a pretty straight forward thing to do that most people do naturally. Its literally just picking the middle point of the potential search and she didn't even do that correctly after the first 2 guesses. Thats why Balmer got screwed up on the high low when she said 60 - he was expecting 62/63. I think he may have even changed the number because she started deviating from what he expected.

This isn't really a leetcode style problem, but i would rate it on the easier side of medium. You just need to know that the optimal strategy is a binary search and that the time complexity of a binary search is worse case O(logN). Therefore, the person proposing the game has an optimal strategy which makes the binary search go to its worst case. The expected required search time would therefore be log(100) = 6.64. At this point, the player is losing money.

@@jopmota This question was oriented towards evaluating a programming mindset and was a pretty basic example of a question that you might pose to a Dev. But the interview process "back in the day" wasn't solely "brain teaser" questions. There was also plenty of digging into past work and experiences as well as skill evaluation and "team compatibility". When questions like these were asked it was primarily to evaluate "how" the interviewee approached the problem - not necessarily whether they came up with the answer to the problem that you expected. (I rarely used questions like this when I was interviewing people, though I did have friends that used them.)

correct. You need 7 tries (it's between 2^6 = 64 & 2^7 = 128 so 7 as the integer closest to number of tries to reach 100) to find the number by binary search so you're always going to lose money, unless you get lucky. Ballmer's "explanation" about more numbers to lose on than to gain is either misinformation or he doesn't understand the binary nature of the problem (which I find hard to believe since he was a math major)
@mikemcmillan6 жыл бұрын
That's right, but the interesting twist is that the guesser should expect that the person she is playing against will choose the worst case as their number. This let's you skip the binary search and only guess numbers which requires the maximum number of searches.

@str8dominican5 жыл бұрын
For the the people saying this is a stupid question sit down and pay attention, you might learn something: This isn’t some dumb game. He’s testing your ability to solve problems and more specifically your ability to apply known computer science algorithms to real world problems. The question is should you play the game, or better put, are you likely to win?, he’s not testing whether you say yes or no but HOW you come up with the correct answer, which is NO, you should not play. Answer: you have 5 tries to pick correctly before you start loosing money, so you want an algorithm that is very efficient. In this case the most efficient algorithm would be a binary search which has a big (O) of n log n. 2^5 = 32 but the list is a 1-100 which means it’s possible that after 5 choices you still won’t have the correct number. 2^6 = 64, that’s still not enough . 2^7 = 128, which is more than 100, and that’s perfect. So with binary search the most it could ever take is 7 tries to get the right answer. It could be less but worst case scenario is 7. The problem is he knows we’re using binary search because it’s the most efficient way, but since it’s a known algorithm it has very specific rules about which numbers to select. He can pick a number that will guarantee that we use all seven picks to get the right number. But we start losing money after 5. Therefore, no, you should not play the game. Programming is about solving problems. If you can’t handle or apply such a basic algorithm why would they intrust you with handling much more complicated problems at their company.

If you want to know the _actual_ exact answer, you calculate the expectation value where you multiply the probability of the occurrence times the money gained or lost from each case. The full calculation is: = 1/100 * (2^0*5 + 2^1*4 + 2^2*3 + 2^3*2 + 2^4*1 + 2^5*0 - 37*1) = $0.20 per game. Basically, each round the number of ways (out of 100 possible random numbers) that you could get the right number increases by a factor of 2. So there's 1 way to get it right on the first round (answer 50), 2 ways on the second round (answer 25 or 75) and so on until after the sixth round (which is 2^5 ways). Up to this point, you have had 63 opportunities to get the correct answer. Assuming you've played optimally but didn't win by the sixth round, you will be guaranteed to win on the seventh round which has 37 numbers left. Of course, this all assumes that he randomly chose the number. He can obviously choose a biased number if he wants which changes everything.

In the actual job interviews, I'm fairly certain that they phrase it differently so that the expectation value is different and negative. Ballmer just said it incorrectly here. He should have said that the guess after the $1 prize would instantly be a $1 loss, not a $0 wash. This would make you subtract 2^5 and 37*2 instead of only subtracting 37. The expectation value in this new situation would be -$0.49 so you wouldn't play the game if it was phrased in this way. Ballmer just fucked up here.

Microsoft wants to know if you can solve a bite-sized intellectual teaser in the moment. Amazon wants to know if you have exhibited a pattern of behaviors over time that align with their leadership principles. The Amazon approach is much better. IMHO.

first he says the number will be between 1 and 100, the statement is exclusive meaning the pick will be 2-99, so 98 possible choices. with binary search you would get 1x$5, 2x$4, 4x$3, 8x$2, 16x$1, 32x$0, 36x$-1. calculating the expected value using above (outcome / 98 * dollar value) added up you get ~$0.21. therefore statistically take the chance. BUT he doesn't say he will pick a number at random, so it could just be say no bc he will pick one of the 36 negative value options.

If you want to know the _actual_ exact answer, you calculate the expectation value where you multiply the probability of the occurrence times the money gained or lost from each case. The full calculation is: = 1/100 * (2^0*5 + 2^1*4 + 2^2*3 + 2^3*2 + 2^4*1 + 2^5*0 - 37*1) = $0.20 per game. Basically, each round the number of ways (out of 100 possible random numbers) that you could get the right number increases by a factor of 2. So there's 1 way to get it right on the first round (answer 50), 2 ways on the second round (answer 25 or 75) and so on until after the sixth round (which is 2^5 ways). Up to this point, you have had 63 opportunities to get the correct answer. Assuming you've played optimally but didn't win by the sixth round, you will be guaranteed to win on the seventh round which has 37 numbers left. Of course, this all assumes that he randomly chose the number. He can obviously choose a biased number if he wants which changes everything.

Log of N to the base 2 only gives you the number of minimum seraches which is needed to solve. Great. But, because each search has a different $ value for profit or loss, then you must calculate the Expected value to determine overall profitablility. eg E(X=profit or loss of one round of guessing) = $5(1/100) + $4(1/50) + $3(1/25) + $2(1/12.5) + $1(1/6.25) - $1(1/3.125) - $2(1/1.5625) . . .plug into wolframalpha . . . Since E(X) < 0, (it is actually $-1.03) so stay away. But even if E(x) > 0, there is a practicality of spending your time *if* the expected value for each round of guesses were very small. I am from Canada, so the coversion rate to USD would make this game worse.

The expected value of this game is actually positive if the number is picked uniformly at random (it's 20 cents). So unless you have 1$ in your account, you should play it. Also, if you suspect Balmer is going to pick numbers that make it hard assuming you'll use a simple binary search, you can take that into account and come up with a modified strategy that takes advantage of this to make even more money.
@vixrant3 жыл бұрын
Expected value is -$0.8 . There are 69 negative numbers, 15 positive numbers, and 16 zero payoffs. You are only 15% likely to profit off this game. I've written a program for this if anyone is interested.

If the quiz he asked wash to determine when a candidate decides to step back and think of his/her option to understand their personality, that indicates a preemptive determination factor from interviewer’s perspective and they are only selecting a candidate who thinks like they do. Why go about it through such an abstraction layer?
