Solution: Single Number II
Explore how to apply bitwise XOR operations to identify two unique numbers in an array where all other elements appear twice. Understand using the rightmost set bit to partition the array and isolate the single elements efficiently with O(n) time and O(1) 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.
