Domande per la posizione di Systems Engineer...21 settembre 2012

I thought the interview was all about communication skill... no c c++ java.. no unanswerable questions... no domination... quite cool... he had to see me speaking confidently with out the bias of fear r something else... so he kept the interview cool... of-course, i have tried my best for that... You will be almost selected if u pass the written exam... provided with acceptable communication levels and confidence.. no need of Hollywood level speed or verbal skills... just convey your matter in a cool and simple way.. Take some care to protect your character by answering with contradiction or domination.... if done so.. u have got yourself a job at Infosys...

How many trailing zeros are in the number 5! (5 factorial)?

8 risposte

This sounds like one geared not so much towards getting the right answer, but getting to it the right way. If you think a bit and say "one", the interviewer will know you did it the brute-force way, doing the math. You'd get at the answer faster, and probably impress them more, if you think instead how many times a ten will be produced in doing that math, rather than what the actual result of the math will be. Meno

http://www.purplemath.com/modules/factzero.htm

To generate a zero, we need a (5,2) factor pair. For any given number N, we have at least N/2 number of multiples 2, so the number of zeroes can be determined by the count of numbers that have 5 as a factor (i.e we have more 2s than 5s) Roughly, we can count N/5 numbers that are multiples of 5, add to that numbers that are multiples of 5^2 (these will have two 5 factors) i.e N/25, add to that numbers that are multiples of 5^3 (these will have three 5 factors) and so on. For eg: 10! -> 2 multiples of 5 -> 2 zeroes 100! -> 20 multiples of 5 + 4 multiples of 25 -> 24 zeros 500! -> 100 multiples of 5 + 20 multiples of 25 + 4 multiples of 125 -> 124 zeros 1000! -> 200 multiples of 5 + 40 multiples of 25 + 8 multiples of 125 (5^3) + 1 multiple of 625 (5^4) -> 249 zeros Meno

Given a wireless channel with loss rate 0.1, what's the throughput one can get with retransmission.

8 risposte

It can modeled as binary symmetric channel. As to my understanding, channel capacity can be acheived with perfect feedback and simple retransmission scheme, so i guess the answer is 1-H(0.1). Meno

10/(1.23456...)=8.1 packets per sec

Interviewer was correct. With probability 0.1 you have one retransmission, with probability (0.1)^2 you have two, etc., since you can also lose the retransmitted packets, reducing the throughput to approximately 0.89. Meno

identify the number of 1s in an integer is odd or even

7 risposte

Was taken from: http://graphics.stanford.edu/~seander/bithacks.html unsigned int v; // word value to compute the parity of bool parity = false; // parity will be the parity of v while (v) { parity = !parity; v = v & (v - 1); } Meno

Above solution is incorrect. void OnesAreOdd(int n) { int i=0; while(n!=0) { n=n&(n-1); i=i^1; } return i==1?true:false; } Meno

Let number be c int count = 0; while ( c != 0 ) { count += (c & 1); c >> 1; } if ( count%2 == 0) printf("Number of 1s are even); Meno

There is a body of water that starts with 1 square unit, and doubles in size every day (2 units after 2 days, 4 units after 4 days). It takes 100 days to fill up. How many days would it take to fill if you started with 2 square units?

6 risposte

100 - 1 = 99 days

Starting with 2 square units at time t=0 is like 1 square unit at t = 1. [this logic is the key to answering the question]. Now let's do the first few cases. t = 0: size = 1+1 = 2 t = 1: size = 2(1+1) = 2+2 = 4 = f(2) in the 1 unit case. Pretty easy to see it only requires 1 time period less from here. The OP was right. Meno

This question is phrased incorrectly. I think you meant "4 units after 3 days". Which makes your answer wrong as well. This is not helpful at all. Meno
