The twelfth post of the series of programming job interview challenge is out, 28 readers provided answers to job interview challenge #11. I have to admit that I probably failed explaining what I was looking for in challenge #11, because I asked you to provide the best algorithm in both manners: performance and memory. What I really meant is that performance is most important but don’t neglect the memory issue. Due to my little “embarrassing failure”, there are two groups of correct answers – the performance oriented and the memory oriented.

The correct answer which I was looking for (best at performance) as Alex, the first one to provide a detailed solution (its two times in a row), wrote:

We surely don’t want to release a software that will crash ungracefully due to such a case. Fortunately, the .Net framework makes it possible to […]
