Your solution returns wrong answer for inputs like [3, 2, 2].

Your solution has a bug, it is not a kata issue.

I have solved this kata in c# and initial test has passed...but when I (Attempt), I get an error says :

Test Failed
Expected: -1
But was: 5
I've tried my solution on VS code and it worked properly.
I don't know what's wrong!
I also want to know if the sample test written down the page is exactly what causes the error? cuz I tried this particular case in vs code and it passed successfully.

(OP was referring to the initial code, which would not compile) Fixed.

the return statment should have a semi colon: (in java) INCREDABLY minor issue.

how?

You definitely can, and it seems that you did...

Why

this kata is so bad bruh delete this sh

I used a Set, not the same way you did though

For some extrange reason, I thought the kata has to check if the number of instances is a PRIME number instead off ODD (realized when i saw the solutions from others), but somehow i passed the tests hahahahahahaha so don't trust my solution

nvm

Same

Ok for Python.
