PM your answers. Dont post it here.

Really? :rofl:
I did not think that it would pose that much
of a problem for the coders around here. :eek:

If you post it here and you are right there is no point in anyone else figuring it out.

I never actually thought about posting a solution,
but just assumed that an answer to the question…

“Can you crack it?”

…was what you required. :winky:

Maybe this will help some folks:

<?php declare(strict_types=1);
error_reporting(-1);
ini_set('display_errors', 'true');

function fred($val)
{
    foreach($val as $num) :
      echo ' &nbsp; ' .$num;;
    endforeach;    
    echo '<br>';
}

$x1 = [6, 8, 2, ' - one correct and well placed ']; // 
$x2 = [6, 1, 4, ' - one correct and wrong placed'];
$x3 = [2, 0, 6, ' - two correct and wrongly placed'];
$x4 = [7, 3, 8, ' - none correct'];
$x5 = [3, 8, 0, ' - one correct and wrong placed'];

fred($x1);
fred($x2);
fred($x3);
fred($x4);
fred($x5);

Output:

Edit:

Spelling not my forty :frowning:

How is that going to help when you got the numbers wrong?

I found it easier to validate my attempts by having the following test at the start:

$x0 = [1, 2, 3, ' - attempt 001']; //

I have no idea what you are doing and there is no 380.

I found it easier to find the solution when the hints were nicely line up on the screen.

Whoops - it should have been “7 8 0”.

Congratulations to @m_hutley for being the first one to get it right.

John - This cant be correct if “7 3 8” 's result is “Nothing is correct.”

He meant the numbers in the last hint box.

Cant be doing too bad, you are the only one to get it right.

Let me know if you “close” this at some point, @benanamen, and i’ll come back and give my way of figuring it out (Which is NOT saying that it’s the only way. Just how my mental gymnastics worked). In a spoiler block, of course.

You can tell me in PM if you like. I am interested to know how you did it.

John Betong cheated and used google to find the answer.
