Problem: Sliding Window Maximum
Explore how to find the maximum values within a sliding window of size k in an integer array using a monotonic deque. Understand each step to implement a queue-based approach that iterates through the array while maintaining the maximum in amortized constant time and minimal space. By the end, you'll be able to solve this problem with O(n) time complexity and O(k) space complexity.
We'll cover the following...
Statement
Given an array of integers nums and an integer k representing the size of a sliding window, the window starts at the leftmost position of the array and moves one position to the right at each step until it reaches the rightmost position. At each position, the window covers exactly k consecutive elements.
Return an array containing the maximum value within the sliding window at each position.
Note: The result array will have exactly
nums.lengthelements, one for each valid window position.
Constraints:
nums.length...
