stuff like

do i have some setting wrong in visual studio or am i using the wrong version of visual studio(using 2017)?
I had those issues with VS 2015, but I am not experiencing them on VS 2017.

^ update to latest version of visual studio


@NightFighter
I got about 49ms on your latest test.

I'm assuming chilly will be talking nano seconds when it comes to his solution. Might look into ways to optimize this during the week if I get the time. Optimization sorcery is not my strong suit tho

Well on my third attempt at coding it I get

Code: Select all

PASS (12.17ms) File Test: Buck Futter's Sexy Test 1
PASS (6.59ms) File Test: Buck Futter's Sexy Test 2
PASS (6.28ms) File Test: Buck Futter's Sexy Test 3
PASS (5.15ms) File Test: Buck Futter's Sexy Test 4
PASS (5.61ms) File Test: Buck Futter's Sexy Test 5
PASS (5.96ms) File Test: Buck Futter's Sexy Test 6
PASS (359.39ms) File Test: NF Test
PASS (280.43ms) File Test: NF Test 2
it's not bad, but nowhere near what you are getting :(
I think I'll throw in the towel now.
[Edit]
does chili's cpu run things faster with 4 threads or 8 threads; because it is a quad core cpu but it has 8 logical processors

From my testing, I had the best results from utilizing 8 threads for the i7 4770k.

Looks like i''m done for now. These are my final results.

@yum

Yeah, the base fast algo is very simple indeed, so it's highly possible that you missed nothing and just submitted the expected solution.

And I don't think you'll be disappointed by the optimizations ;)

For heavy tests, instead of generating and loading giant files my recommendation is inherit from TestCase and make a test case that fills a vector in memory without need to access any file. Faster and easier than writing separate code to generate the data set file in the first place :D
