maximum number of the current window subscript. Each cycle, the number of deque less than nums[i] is excluded. Add the subscript of the right edge of the window to the deque, while rejecting the ordinal of the deque head crossing.

windows with a linkedlist. If 3 appears, then 1 is not likely to be the maximum value. So you can remove 1. Then-1 appeared. You cannot remove 3 at this time. Because 3 can be the maximum value. That is, if the number of occurrences is larger than the number that appears first, the previous number can be deleted. When the index at the top of the list exceeds the window
