Engineering Interview Questions in Bridgeport, CT

Initially I gave a naive answer which had two booleans and 3 "if" statements which checked for i%15==0, i%3==0, i%5==0, respectively. Then the interviewer asked me whether this could be reduced to two if's. I thought it couldn't, and then she asked me what would happen if I got rid of the check for i%15==0. Then I realized, that we could achieve it through string concatenation (i.e., not printing a newline for every "fizz" or "buzz") The answer was this (in Java) public void fizzBuzz() { for (int i=1; i<=100; i++) { if(i%3==0) System.out.print("fizz"); if(i%5==0) System.out.print("buzz"); } } The trick in the question is that due to the way it's worded, you are tempted to think that you need three conditions. Actually, you only need two. It was a little embarrassing to have slipped in this problem, but I'd been so used to printing lines in C++/Java that I forgot the print statements could be used in this manner. I later googled it and found it is a common interview question.
