说明：  求出sliding window的最大最小值(n array of size n ≤ 106 is given to you. 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 rightwards by one position. Following is an example: The array is [1 3-1-3 5 3 6 7], and k is 3. Window position Minimum value Maximum value [1 3 -1]-3 5 3 6 7 -1 3 1 [3 -1 -3] 5 3 6 7 -3 3 1 3 [-1 -3 5] 3 6 7 -3 5 1 3 -1 [-3 5 3] 6 7 -3 5 1 3 -1 -3 [5 3 6] 7 3 6 1 3 -1 -3 5 [3 6 7] 3 7 Your task is to determine the maximum and minimum values in the sliding window at each position. )
