On #9, is it 16-bit or 64-bit values? Sounds like you may have been answering a different question. Isn't the standard answer to use a 65536 entry lookup table?

Edit: oh, are you reinterpreting the array of 10000 16-bit integers as 2500 64-bit integers? But then what operation do you use on each?

Either way, if you find yourself arguing with the recruiter, it's probably a bad sign.

Yes, it is, but is it such a common knowledge?
