题解:
func nextGreaterElements(nums []int) []int {n := len(nums)ans := make([]int, n)for i := range ans {ans[i] = -1}stack := []int{}for i := 0; i < n*2-1; i++ {for len(stack) > 0 && nums[stack[len(stack)-1]] < nums[i%n] {ans[stack[len(stack)-1]] = nums[i%n]stack = stack[:len(stack)-1]}stack = append(stack, i%n)}return ans
}
