• Testing for 'tHese guIdElineS aRe deSIgneD tO Be CompAtiBle wItH joe cELKO’s sql prOGraMming StYLe boOk' to be actually random

sample: tHese guIdElineS aRe deSIgneD tO Be CompAtiBle wItH joe cELKO’s sql prOGraMming StYLe boOk

Expected: true
Actual: false

for sample test case.

Also I am not pretty sure if my code does what I meant.

std::default_random_engine prg; // prg stands for pseudo random generator 
  std::uniform_int_distribution<int> int_distribution(0, 9);
  
  for (int i = 0; i < x.length(); i++) {
    int random = int_distribution(prg);

this was meant to give random number every iteration, and therefore create random case.
But when I recompile my program I see, that in every single compilation those numbers, are exactly the same. Like drawing them happens only one time. Therefore my "random case" is random only for first compilation, and then it looks exactly the same after another compilations. At least it looks like in my OS - Mint, GCC 5.4.0

phh, I guess I have to find another way to generate "random" numbers ;]

after 3 months it is still broken ;<

Thank you so much for your reply! So there is no reason to reivent the wheel trying to write some code on your own, which have same functionality as this already written and saved as functions in language libraries, right? I gotta trust that if there is built-in function it is most efficient and most safe for all purposes, is that correct?

upvote!

No I don't. I pass sample input, and most of random tests, but there is always one that stops me.

treat this as a part of practicing. You aren't always getting super-duper perfect clear docs, are you?

Hi - Python here.

I pass loads of random tests, but there is always one that stops me. When I run my code in other interpreters everything looks fine, output is correct. What can I do to make my code pass random tests? How can I debug, so I can see what is output of my code here, in CodeWars interpreter?

If you have any idea, please help me.
I appreciate, thank you, xoxo.

'even numbers must be on their places'

while attempting I am getting this:

#INPUT:
[1, 20, 2, 28, 3, 5, 7, 9, 18, 50, 11, 74, 13, 52, 15, 56, 44, 78, 72, 17, 24, 0, 19, 26, 38, 21, 36, 23, 10, 88, 25, 66, 70, 54, 27, 6, 60, 29, 31, 33, 35, 92, 37, 39, 41, 40, 43, 76, 45, 47, 49, 86, 22, 51, 53, 16, 90, 8, 68, 55, 57, 59, 96, 98, 80, 61, 64, 63, 58, 32, 65, 67, 14, 69, 71, 73, 48, 75, 77, 30, 79, 4, 42, 82, 81, 83, 85, 62, 87, 12, 89, 91, 46, 84, 93, 95, 34, 97, 94, 99]
should equal
#OUTPUT:
[1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99]

how is that possible? Why even numbers are just erased from ouput array?

I am doing Python btw.
