Problem: Sliding Window Maximum

hard
40 min
Explore how to apply the sliding window technique to efficiently find maximum values within a moving window across an integer array. This lesson guides you through understanding the problem constraints and implementing a solution that optimizes both time and space complexity, helping you solve this common coding interview pattern with confidence.

Statement

You are given an array of integers nums and a sliding window of size w that moves from left to right across the array, shifting one position at a time.

Your task is to find the maximum value within the current window at each step and return it.

Constraints:

  • 1≤1 \leq nums.length ≤103\leq 10^3

  • −104≤-10^4 \leq nums[i] ≤104\leq 10^4

  • 1≤1 \leq w ≤\leq nums.length
