Re: Problem 008

Thanks sjhillier and I agree with your feeling that the wording is not necessarily misleading if one keeps in mind that the problem refers to a "number" , not to a two-dimensional array...

Re: Problem 008

Absotively , although, without checking, 9989 may also appear elsewhere (or even 9999) "adjacently," only because the 1000-digit number is not presented as a number , "consecutively" and "contiguously(?)"...

Final (Anti-Climactic) Report: The "Original" and "Improved" codes find the 10 millionth prime number (179,424,673) in 3,929 and 3,928 seconds, respectively; so, at least the "All New and Improved" code is not slower(!!) but, it's not exactly "Improved" either; and, still being surprised only shows...

Thanks! rayfil ... "Assuming" I understand you right: 1) In the "Original" algorithm I was disregarding further processing of all even numbers, but only at the expense of first executing "else if(i % 2 == 0) return false;" for every even number, which, though relatively quick, I'm sure (You are way...

Re: Weird runtime behavior

I've noticed from time to time in the past that my RunTimes have counterintuitively increased rather than decreased.
