Sliding Window Maximum
Detailed guide and Python implementation for the 'Sliding Window Maximum' problem.
Problem Statement
You are given an array of integers nums and an integer k representing the size of a sliding window which moves from the very left of the array to the very right. You can only see the k numbers in the window. Each time the sliding window moves right by one position.
Return the max value in each sliding window.
Write a function maxSlidingWindow(nums: List[int], k: int) -> List[int].
- •1 <= len(nums) <= 10^5
- •-10^4 <= nums[i] <= 10^4
- •1 <= k <= len(nums)
Examples
nums = [1, 3, -1, -3, 5, 3, 6, 7], k = 3
[3, 3, 5, 5, 6, 7]
Window [1,3,-1] max=3, [3,-1,-3] max=3, [-1,-3,5] max=5, [-3,5,3] max=5, [5,3,6] max=6, [3,6,7] max=7.
nums = [1], k = 1
[1]
Single element window, max is 1.
