when the input is this 3,2,3,3,5,6,5,2 so how we find the unique number using bitwise XOR operators?? and how we manuplate

Statement of the question defines the input method clearly.
On the question, you have a input that is only present once & all others are present in the same out.
It’s like odd one out.

There are some end conditions to the questions so that they can have a particular answer.
