This has piqued my interest, I'm slightly familiar with C and Python, do you (or does anyone) know of any sort of review of resource optimisation for a simple program (like fizzbuzz)? To me, naively, it seems like the bigend would fit in a register and so memory use wouldn't increase noticeably if you used some sort of double integer type. So it's it processor bound?
