Thanks for your reply but this does not explain why Order use raises this error and most topic (mostly stackoverflow) are addressing different issues.
Order and OrderBy as both part of Linq assembly normally. So why OrderBy will be defined and Order not, unless Order has been depracted in the language version of the kata.

C# experts is it that normal i have this message with System.Linq, System.Collections and System.Collections.Generic directives included in my solution ?
error CS1061: 'IEnumerable' does not contain a definition for 'Order' and no accessible extension method 'Order' accepting a first argument of type 'IEnumerable' could be found (are you missing a using dire

What happens to sort method on array for JS with this kata ?
Array.sort is not working and leave array unmodified. Kata does not specify blocking anything

I am having an error System.FormatException : Input string was not in a correct format.
This is on the unit test code line cdecode.Helper.Array2DToString(ClosestWeight.Closest(s))
The code itself run without any error and i have not change the output type so i am returning
int[][] and here the return return new int[][] { result[index], result[index+1]};
I guess the Helper method is from Nunit frawework but quick search unsuccessful. So what could cause the cdecode to throw error ?

Still BigInt capabilities are not disbled for some language. Kata translation should take this into account.

I have introduce a typo when trying to report the issue but yes it is definitvely C# code not in any other language. If you look on google many people having similar issue.
Any way same code copy / paste on codewars again and it is runs !!

Hey
New to c# and i have a code that run on my pc but when i move it here, i start having different errors which is really strange for me

Thing as could not convert int to string ex: 'long' does not contain a definition for 'toString' and no accessible extension method 'toString' accepting a first argument of type 'long' could be found (are you missing a using directiv and so on. Same for toCharArray,

Convert inacessible though system namespace being included

I don't have any complex setup on local

That is all have so question is why i am having these kind on basic object reference error ?

Who vote best practises and clever ??

BigInt kind of api should be disabled for all language. Why only java ?

After some analysis, sequence rules allow me to find a solution. But feel like
there is a permutation/combination topic or approach that would like to get.
Any explanation or link to lean is welcome

Hello 4 years later if someone else is back on codewars here

1. How many random test is there and is it possible to improve random test fails message (log) for instance adding what is expected

Testing for :
n : value , result : expected

2. Perfomance tips
   Any advice is welcome as no idea of solution to speed up a little bit my code.
   When i see fails with testing for ... what that is mean ? These values those not tested because of perfomance or failure ?

Stuck on this error ' should be able to subscribe and unsubscribe in handler code' and getting three fails
Could anyone explain me, I am sure missing something in instruction et the description above !!

Who solved this kata recently? I finally realised that illegal access is related to heap size. Ok my code might note be efficient but how can I run out memory for an input of size 5 ? I check the first input size and it is 5. If then so, i could even pass teh basic test case. Please something is wrong there.
