3285. Find Indices of Stable Mountains

There are n mountains in a row, and each mountain has a height. You are given an integer array height where height[i] represents the height of mountain i, and an integer threshold.

A mountain is called stable if the mountain just before it (if it exists) has a height strictly greater than threshold. Note that mountain 0 is not stable.

Return an array containing the indices of all stable mountains in any order.

package main

func stableMountains(height []int, threshold int) []int {
	res := []int{}
	for i := 1; i < len(height); i++ {
		if height[i-1] > threshold {
			res = append(res, i)
		}
	}
	return res
}
