Implement queue-based algorithms and data structures

Create implementations for queue-based algorithms and data structures:

## Basic implementations:
- Queue using arrays (circular array)
- Queue using linked lists
- Priority queue implementation
- Deque (double-ended queue)
- Queue using stacks

## Classic queue problems:
- Level order traversal of trees
- Sliding window maximum
- Implement LRU cache
- Generate binary numbers from 1 to n
- Rotten oranges problem
- First non-repeating character in stream
- Josephus problem

## Requirements:
- Provide optimized implementations
- Create comprehensive test cases
- Include complexity analysis
- Demonstrate practical applications

This collection will cover fundamental queue operations and their applications in solving algorithm problems.

Start by reviewing the repository's existing algorithm and data-structure organization and conventions. Implement the listed queue variants and classic queue problems, then add comprehensive tests, complexity analysis, and practical-application demonstrations. Done means the requested implementations are covered and verified by tests.
