@java_coffee_cup there is a comma instead of a period in multi-path 2, 2nd level in, 3rd line from bottom of level

Have it fixed. Thank you.
Hello,
I pass all the tests and validators except validator 8 and Iām a bit lost as to whyā¦ Is there something special about this one ?
This map is similar to the test case. Relatively there are more open spaces. Perhaps you have to check will some more spaces cause timeout/memory-out in your program.
I ran a few tests and I donāt think the issue is a timeout, even though I donāt see what else it could beā¦
Thanks anyway
Hi,
great puzzle !! ;o)
But seems im in dead end ;o( becouse:
I have all passing test cases but #06: 13ās Cube with result:
Failure
Found: 57
Expected: 95
(so is possible that my code found shorther path? or its for sure bug in my code?)
But when i submited my code, i got error @
#01: Example Validator
#08: Multi2 Validator
but āproblematicā #06: 13ās Cube Validator is green.
I really donāt know what to do more. Is there any way how to get some additional debug/test info or is possible to review these test cases?
Thanks in advance for any reply and/or advice @java_coffee_cup .
Have a nice day.
Found it 
!
Sorry for bothering 
Great to have found the problem by your own effort. 
If possible you can share the kind of issue so that others may have an extra point to pay attention with.

Glad to. Its combination of two āedgeā cases.
- This puzzle in compere with many others do not contain āboxingā wall around inputed space:
:#####
:#+++#
:#+++#
:#+++#

- In PHP lets have array:
$var = [ āAā, āBā, āCā, āDā];
then
$var[ -1 ]
is undefined.
But in case of string:
$var = āABCDā;
array access style to this string, again:
$var[ -1 ]
will return āDā ā last character from string (similar to substr() behavior).
So i accidentally created magically rounded flat space, where in following example is possible to move from [0][2][z] to the LEFT to position [3][2][z].

Just create the box. Thatās what I did.
Yeah, also possible.
I added condition for āXā axis (Y,Z was fine).
if( X < 0 ) skipā¦
Hi there, Iām somewhat of a beginner at this platform, and this is my first medium puzzle I try to complete, and Iāve tried it because Iām learning about A* algorithm, and Graph Traversal algorithms, at the University, and this seemed like a good puzzle for practicing both things. I cannot pass tests 6,7 and 8, because my program doesnāt find any path. Is there some specific ātrapsā in these tests, that can make this happen? If not, is there anyway that someone can help me find the errors on my thought process? Because Iāve checked my code for some hours now, and checked my thought process, and I cannot find my errors. It may be because of sleepyness, or just because of me being a noob! xD
A* is a bit too complicated for this puzzle.
Try BFS, itās enough.

Thank you, I will try it. 
Will say, if I get stuck again!
Just to let you know, that like you suggested, Iāve done the BFS way, and now itās done. Also changed from C to Python just to practice, and I think it helped a little xD
Thanks man.
Hi. Also having issues with Multi2 Validator. Headed your advice and took TestCase Multi-Path 2 and made bunch of empty spaces into it. Yet, no timeouts. Any ideas? All other validators are ok.
I coulnāt understand what is considered āscapeā in the question.
When do A and S are considered free of danger? in which cell?
Not quite understand your question.
There is no word āscapeā in the puzzle.
Similarly, the statement did not mention A, S, or any other cells are in danger, or not in danger.
It did mention the team can walk through the cells in a constant speed. The shorter the path, the faster they can reach the target.
Ok, forget the word āscapeā, I couldnāt understand what is condsidered a target. Is it a specific point (x,y)?
