Issue Description

I would like to add a solution for the LeetCode problem "Binary Tree Level Order Traversal II" (Problem 107) to the project. This problem involves performing a level order traversal on a binary tree but returning the node values in reverse level order.

1. Clear and well-documented code.
2. An explanation of the algorithm and its complexity.
3. Example test cases to demonstrate the correctness of the solution.
