Solution: Single Number II
Explore how to solve the Single Number II problem by using bitwise XOR manipulation to identify two unique elements in an array where others appear twice. This lesson teaches you to leverage the rightmost set bit for partitioning data and solving efficiently with 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.
