Solution: Single Number II
Explore how to identify two unique elements in an array where all others appear twice by using bitwise XOR operations. Understand the process of isolating a rightmost set bit to separate elements into groups and learn to implement this pattern efficiently with constant space complexity. This lesson enhances your problem-solving skills in bitwise manipulation and algorithm optimization.

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.
