In this solution even test cases won’t give the result as expected for the unique number?

It’s already mentioned that there is only unique number in given test cases.
It says there are 2n+1 numbers where every number occurs even number of times except one.
This particular xor trick is supposed to work only on such test cases. Not on a testcase that you have given.
