 Division method without using divide operator5 Answersint divide(int a,int b){ //should return a/b if (b == 0){ throw new DivisionByZeroException(xxxx);} // or do whatever... if (b == 1){return a;} int i = 1; int temp = b; while (tempi++ should be before temp=b*i, sorry for errorThe other way is to use bitwise operation (>> or >), you are doing division of 2. For example, 01000 represents 8 00100 represents 4 00010 represents 2 00001 represents 1 Hopefully you can understand this.... However, you need to take care of when the denominator is odd- which is very difficult to do. I would recommend my first solution listed above. It is more understandable or less error-prone.Show More ResponsesUse >> to shift both until divisor is 1, the final dividend value is the answerSomeone from Symantec gave me information about what to expect in the job interview at Rooftop Slushie. https://wwww.rooftopslushie.com

 I have 9 coins, out of which 8 coins are identical in weight and one is lighter in weight. Is it possible to find the light weight coin with only two weighings, using pan balance?2 AnswersYes, in 2 weighings.Yes. Put 3 on one side, 3 on other and set aside 3. If the pan tips, the lighter group rises up, if equal, the lighter group is on table. Once you find the lighter group of three, use the same tactic, one coin on table, one in each pan. If it tips, you found the lighter one, otherwise it is on table. Same question is asked with balls and with groups of 8.

 What is the range of numbers that can be stored using a single byte?2 AnswersSigned: From ?128 to 127. Unsigned: From 0 to 255.I think the range can be anything you want it to be, just have to agree on the storage format. Imagine a situation where you have to store only the even positive numbers, that means the range can be 0..512. If you know that the lowest number can be 100, then the range can be 100..612. Using more elaborate formats you can encode any range in a byte (with low precision, possibly).
