my understanding was that 1 was moved, but this is a 2 byte register, so 2?

How many bytes are moved in the following line of your solution?

  mov cx, [rdi+rsi]   ; char = string[index]

My code works on all the default tests, not on the should_work_for_more_fixed_assertions tests. No idea why

I see from other solutions that the Linq option I was missing hardly was 'ThenBy' to sort the names inside List.

You cannot! But I can't stop anyone adding a polyfill..

Finally addressed this... Stopped the use of require.

Added the note, thanks for the suggestion :)

Please provide the note in description that the use of 'BigInteger' classes is banned BEFORE user attempt the test.
I understand it's kyu 4 so no simple solution can be used here, but it should be clearly noted- not something I see when I'm already attempting the final solution.

Upvoted- thanks for this tip. I completely missed that word and ended up with some tests failure.

@FArekkusu - your drawing is deceptively misleading. First off, the kata does not explain that there could be obstacles in the path. Secondly the path to get to the target, with the obstacle, would be

NORTH WEST WEST SOUTH SOUTH SOUTH EAST EAST

and

SOUTH SOUTH 

without the obstacle.

I'm sure you can cook up an example with an obstacle (perhaps a one way door?) where the paths

  NORTH SOUTH EAST WEST 
  NORTH EAST WEST SOUTH 

(or similar) are not equivalent.

The kata is ill-posed because the it gives the impression of a single algebraic set, but the test uses two separate sets.

Please consider updating the kata description to clarify the intent. Thanks.

I agree! Would be a less trivial problem to solve too.

Found it... I was not checking for one othe kind of null input

Hi,

What does

"should_work_for_edge_assertions
Test Passed
Test Crashed
Exit code: 0
Signal code: 11"

mean?

My code is working for empty string, having '/', '0', '9', ':', starting or ending with a digit....

Em, FArekkusu, didn't you draw ["NORTH", "WEST", "SOUTH", "SOUTH", "EAST"] ?

Check your code.
