- * 239. Sliding Window Maximum
- *
- * Given an array 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.
-
- For example:
-
- Given nums = [1,3,-1,-3,5,3,6,7], and k = 3.
-
- 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
- Therefore, return the max sliding window as [3,3,5,5,6,7].
-
- Note:
- You may assume k is always valid, ie: 1 ≤ k ≤ input array's size for non-empty array.
-
- Follow up:
- Could you solve it in linear time?
-
- Hint:
- How about using a data structure such as deque (double-ended queue)?
- The queue size need not be the same as the window’s size.
- Remove redundant elements and the queue should store only elements that need to be considered.
