Issue is with your skill, not the kata.

The algorithm you've written is way too inefficient for a problem like this. The tests are deliberately written to fail solutions like these. Once you optimize your solution, it should pass in ~2 seconds. You're probably testing with small values on Visual Studio - the tests on Codewars will try massive numbers.

C#, Execution Timed Out but all works good in Visual Studio with same numbers..
c# tests in not optimised..

Only "siay" is fine there.

Expected:"igPay atinlay siay oolcay"
But was: "giPay nitalay siay loocay"
                             ^^^^

Not an issue, your code doesn't follow the specs.

I wroted 100% correct code.. but this kata have some issues.

error:

Expected:"igPay atinlay siay oolcay"

But was: "giPay nitalay siay loocay"

Argument: Pig latin is cool

your code fails to detect some smileys, e.g. ":-D"

From the description:

Each smiley face must contain a valid pair of eyes. Eyes can be marked as : or ;
                                                                               ^
A smiley face can have a nose but it does not have to. Valid characters for a nose are - or ~
                                                                                            ^
Every smiling face must have a smiling mouth that should be marked with either ) or D
                                                                                    ^

You're wrong, the test is fine.

And in the description not all valid and invalid combinations are listed, just a few as examples.

C# Completions 5629

Are you sure they don't work correctly? I don't think so. Please read this before creating a kata issue and provide some proof when you create one.

kata is not working successfully in c#
random test in not working corectly.
I have all suggeted smiles in filter but somehow its not workin 🙄

bro my claps for you👏
but i think Theard-is better.
