Read the task carefully. This is not a valid 3x3 subgrid:

1 2 3
2 3 1
3 2 1

just one random test (below) failing, wants a false. tested manually and on a sudoku solver, the board is correct. it should be true, but expects a false.

{1, 2, 3, 4, 5, 6, 7, 8, 9}
{2, 3, 1, 5, 6, 4, 8, 9, 7}
{3, 1, 2, 6, 4, 5, 9, 7, 8}
{4, 5, 6, 7, 8, 9, 1, 2, 3}
{5, 6, 4, 8, 9, 7, 2, 3, 1}
{6, 4, 5, 9, 7, 8, 3, 1, 2}
{7, 8, 9, 1, 2, 3, 4, 5, 6}
{8, 9, 7, 2, 3, 1, 5, 6, 4}
{9, 7, 8, 3, 1, 2, 6, 4, 5}

in Details tab, one of the example says;

findUniq([ 0, 0, 0.55, 0, 0 ]) === 0.55

but return value is int. So it has to be change.

Good point, wasn't really thinking. As you say, not an issue, kata works as planned.

Why marking it as solved then? Shouldn't you wait for that translator or a power user to solve it first?
Anyway, it's not an issue, L comes before a and T comes before i (capital letters should come before lowercase ones), because that's the expected behaviour in the original language of the kata, javascript.

Post your code

Fixed, thanks

at C#, random tests are failing too.

It should work for random inputs too - Expected: "Lets", But was: "all"
It should work for random inputs too - Expected: "BTC", But was: "Bitcoi***n"

If you saw this message, it just means that you haven't passed all the tests.
