I found the problem statement on the web page link to be a bit "weak". Nothing in the problem statement says that you must do anything other than read in two lines of integers and multiply them in pairs and sum the results ( ie. Dot Product ).
People seem to think that you should sort the data first ( an assumption that is NOT in the problem statement ). Does that mean that you get the problem wrong if you don't sort the data first? Also... it looks as if you have to write the code in one of the listed languages. Is that true? You then submit your "text" code and it is compiled somewhere else? What compiler(s) is/are used and with what settings? This can affect both speed and memory (by large amounts). Also... exactly what does 1.6M for memory mean? For the moment, let's assume that you ARE supposed to sort the data first. Then... at best, all this test really does is check to see if you can read and sort data quickly. Multiplying pairs of numbers is trivial and I doubt many individuals are writing much code to speed up this simple Dot Product calculation. So... unless you write your own integer sorting algorithm that you are very proud of, what's the point of this test (other than it might be worthwhile as a homework assignment to new coders). Have I missed something?
