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.
\n\n\n
Example 1:
\n\nInput: height = [1,2,3,4,5], threshold = 2
\n\nOutput: [3,4]
\n\nExplanation:
\n\nheight[2] == 3 is greater than threshold == 2.height[3] == 4 is greater than threshold == 2.Example 2:
\n\nInput: height = [10,1,10,1,10], threshold = 3
\n\nOutput: [1,3]
\nExample 3:
\n\nInput: height = [10,1,10,1,10], threshold = 10
\n\nOutput: []
\n\n
Constraints:
\n\n2 <= n == height.length <= 1001 <= height[i] <= 1001 <= threshold <= 100Compiled with clang 17 using the latest C++ 23 standard, and libstdc++ provided by GCC 13.
