public class Solution extends java.lang.Object
239 - Sliding Window Maximum.

Hard

You are given an array of integers nums, 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.

Example 1:

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 

Example 2:

Input: nums = [1], k = 1

Output: [1]

Example 3:

Input: nums = [1,-1], k = 1

Output: [1,-1]

Example 4:

Input: nums = [9,11], k = 2

Output: [11]

Example 5:

Input: nums = [4,-2], k = 2

Output: [4]

Constraints:
