This kata is a subject to deduplication process here: https://github.com/codewars/content-issues/issues/136.
Please join the discussion to help us identify duplicate kata and retire them.

C# Function name should use PascalCase (Please refer to implementation of backward compatibility here )

Tell me, what about random tests? I solved the problem and pass the basic tests without any problems. However, my code does not pass random tests, and most importantly, the random test outputs only correct and incorrect results, and the original array is not shown.

JavaScript fork with update to Node 14.x

and language-agnostic description

COBOL translation.

what is best taking performance/memory into account?

• loop first to mapping seen items count and then a second loop to append values according to this counter.
• loop backwards find inside dups to append or not.

It was interesting, thanks.

what parameter is this szout? arrin is for given array, szin is for size of array but what is this szout? plz anyone tell

C Fork kumited.

• updated test suite
• updated format
• eliminated all warnings

Hello The duplicates are removed, but the arrays are not sequence equals. Is it intentional? Expected: [4, 6, 3], instead got: [3, 4, 6] Expected: [4, 5, 2, 1], instead got: [1, 4, 5, 2] Expected: [2, 1, 3], instead got: [1, 2, 3]

Thanks for this Kata series!

PHP translation. Already had to fix a merge conflict :laughing:

hi, for a test case of [2,1,2,3], I get the expted [1,2,3] in jupyter notebook, but not passing it here... any idea why?

Thanks!

please scrutinize for approval

thanks!

PureScript Translation Kumited - please accept :D

There're already enough "remove the duplicate" katas.

I don't see the additional value of this version compared to the normal one, actually... :/
