Pull Request Description
Title: Add Maximum Sliding Window Algorithm Implementation

Overview: This pull request adds an implementation of the Maximum Sliding Window algorithm using a deque (double-ended queue) for efficient O(n) time complexity. The algorithm allows you to find the maximum value in every sliding window of size k in an array of integers.

Key Features:

Efficient Implementation: Utilizes a deque to maintain the indices of useful elements in the current window, allowing for optimal performance.
Input and Output:
Input: An array of integers and a window size k.
Output: An array of the maximum values for each sliding window.
Space Complexity: O(k) for the deque, which holds at most k elements at any time.

Feedback: I welcome any feedback or suggestions for improvements on this implementation.
