yeap, my bad, thx fro your time

...because I verified the tests with other users' solutions again and it's ok

try to read the description again, please

if this is your result 'uiiih uiiih thigh gghs hirih?'., is incorrect

is expected is your result (to equal is a right result).
Are you sure that you got that speech? - "*ow **v **** u oqy t. sopq. qro, qx"
because it's impossible, accordingv to my tests

There are tests errs or did i miss something ?

in one of the test given speech is: "ow v **** u oqy t. sopq. qro, qx", it's length //53
is expected in test 'qow qqqovq ooqqu ooqqu oqqqy ptqqq. sqopq. qropoo, qpx', it's length //54
3d word from 4 symbols (*) grows to 5 (ooqqu)

???

More then it:

given: "*** u**** t**** **s **rh?".length // 27
'uiiih uiiih thigh gghs hirih?'.length // 29

etc.

больше похоже на n^2

i got it, my bad...
thx for your time

1 != 2 != 4 They aren't equal. See the examples in the kata description.

so ?
in my example all are equal except for one(3), if i didn't get it right, explain me pls

All numbers are equal except for one.

findUniq([1,1,2,2,3,4,4])

Expected: 3
instead got: 4

Still doesn't work!
This algorithm couldn't work, it just sorting(arr wasn't change at all) and takes first or last item(arr is still same, just sorted), hello

findUniq([1,1,2,2,3,4,4])

Expected: 3
instead got: 4

Still doesn't work!
This algorithm couldn't work, it just sorting and takes first or last item, he did nothing to solve duplicates, hello
