No way! This would revolutionize math, which is actually bigger than revolutionizing physics and the other sciences. Remember math is the "queen of the sciences," and within math, number theory, which this would turn over, is most highly regarded for purity, beauty, etc (and applies to much physics and of course cryptography). why do I know this? went to school for math anons. didn't say that earlier to not put pressure on myself to solve or be the resident expert. still travelling here.
anyway, here's what i recommend for benchmarking: do a 3 digit c, time the steps, repeat for 4 digit c, then 10 digit, 20 digit, just get some performance data and plot. you will quickly know your time complexity and there are enough programmers here to interpret time complexity, it's integral to CS and math too.
for some strange reason i actually wouldn't mind being stuck at the airport tmr, then i'd have nothing to do but interpret this stuff.
and thanks to baker for posting VQC hints in one place. of course i don't know if this all will turn out but i am still curious enough to be here as are the rest of you, keep up good work
