You are given an integer N and an integer M. You are supposed to write a method void findBestCoinsThatMinimizeAverage(int N, int M) that prints the best collection of N coins that minimize the average number of minimum coins needed to generate values from 1 to M. So, if M = 100, and N = 4, then if we use the set {1, 5, 10, 25} to generate each value from 1 to 100, so that for each value the number of coins are minimized, i.e. 1 = 1 (1 coin), 2 = 1 + 1 (2 coins),..., 6 = 1 + 5 (2 coins), ..., 24 = 5 + 5 + 5 + 5 + 1 + 1 + 1 + 1 (8 coins), and we take the average of these coins, we would see that the average comes out to ~5.7. But if we instead use {1, 5, 18, 25}, the average would come out to be 3.7. We are to find that set of N coins, and print them, that produce the minimum average.

useless questions, not even 1 technical question for a technical role. 1st time in my carrier i have seen an Interview without even 1 technical question shot out & i'm wondering how i got rejected if there is not even one technical discussion happened . It's a time pass show. I hold another offer with another leading aerospace organization before diving in for boeing interview for the same developer position which means the skills sets remains same. Please think 100 times before applying for boeing position. It's a waste of 1 months Plus to know the status of the selection.I feel bad to be part of this Muppets show.
Interview question was given a grid of 9x9 sudoku with numbers filled in already, you have to check if it's a valid suoku.
Basically the interview questions were data structure. The first one was just a simple data structure question, but the second one was mathematical question. I hadn't expected that kind of questions would be asked, so I got really confused. The questions was to prove that Y is a multiple of six, where there are consecutive three numbers X, Y, Z and X and Z are a prime number. I was totally stuck at the point and couldn't make it.
You have a chest of 8 drawers. With probability 1/2, you put a letter in one of the drawers. With probability 1/2, you don't put a letter in any drawer. I open the first 7 drawers, all are empty. What is the probability there is a letter in the 8th drawer?
Given a coin with probability x (= U[0, 1] showing head at each flip, what is the probability that you got a second head after getting the first one.
Die Frage, mit der ich die meisten Schwierigkeiten hatte (die zweite Frage war wahrscheinlich noch ): Finden Sie die zehn meistbesuchten URLs in einem großen Netzwerk von Computern, in dem jeder einzelne die Logfiles der besuchten URLs speichert. (zum Beispiel nehmen Sie viele lange <string (url) -> int (Besuche)> Maps, berechnen Sie die eingeschlossene <string (url) -> int (Summe der Besuche über alle verteilten Maps), und erhalten Sie so die zehn meistbesuchten URLs in der kombinierten Map) Die Ergebnisliste muss genau sein und die Maps sind zu umfangreich, um sie über das Netzwerk zu übermitteln (vor allem ist es nicht erlaubt, sie alle an den zentralen Server zu senden oder direkt mit MapReduce zu arbeiten)
