题解：

func maxSlidingWindow(nums []int, k int) []int {n := len(nums)prefixMax := make([]int, n)suffixMax := make([]int, n)for i, v := range nums {if i%k == 0 {prefixMax[i] = v} else {prefixMax[i] = max(prefixMax[i-1], v)}}for i := n - 1; i >= 0; i-- {if i == n-1 || (i+1)%k == 0 {suffixMax[i] = nums[i]} else {suffixMax[i] = max(suffixMax[i+1], nums[i])}}ans := make([]int, n-k+1)for i := range ans {ans[i] = max(suffixMax[i], prefixMax[i+k-1])}return ans
}func max(a, b int) int {if a > b {return a}return b
}
