LeetCode - 150 - Sliding Window Maximum

The problem You are given an array of integers nums, and there is a sliding window of size k which is moving 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 sliding window. Examples Input: nums = [1,3,-1,-3,5,3,6,7], k = 3 Output: [3,3,5,5,6,7] Explanation: Window position Max --------------- ----- [1 3 -1] -3 5 3 6 7 3 1 [3 -1 -3] 5 3 6 7 3 1 3 [-1 -3 5] 3 6 7 5 1 3 -1 [-3 5 3] 6 7 5 1 3 -1 -3 [5 3 6] 7 6 1 3 -1 -3 5 [3 6 7] 7 Input: nums = [1], k = 1 Output: [1] Constraints 1 <= nums.length <= 10^5 -10^4 <= nums[i] <= 10^4 1 <= k <= nums.length Explanation Before we jump into the solution, let’s look at our example with nums = [1,3,-1,-3,5,3,6,7], k = 3 We can see that at the first position we have max value 3, which we add to our output array. ...
