Solution: Single Number II
Explore how to solve the problem of finding two unique numbers in an array where all other elements appear twice using bitwise operations. Understand the XOR technique that separates these numbers by identifying a distinguishing bit and how to implement this in linear time and constant space.

Statement
Given a non-empty array arr, in which exactly two elements appear once, and all the other elements appear twice, return the two elements that appeared only once.
Note: The result can be returned in any order. The solution should use only constant extra space.
