n buildings in a line. You are given an integer array
heights of size
n that represents the heights of the buildings in the line.
The ocean is to the right of the buildings. A building has an ocean view if the building can see the ocean without obstructions. Formally, a building has an ocean view if all the buildings to its right have a smaller height.
Return a list of indices (0-indexed) of buildings that have an ocean view, sorted in increasing order.
Input: heights = [4,2,3,1] Output: [0,2,3] Explanation: Building 1 (0-indexed) does not have an ocean view because building 2 is taller.
Input: heights = [4,3,2,1] Output: [0,1,2,3] Explanation: All the buildings have an ocean view.
Input: heights = [1,3,2,4] Output:  Explanation: Only building 3 has an ocean view.
Input: heights = [2,2,2,2] Output:  Explanation: Buildings cannot see the ocean if there are buildings of the same height to its right.
1 <= heights.length <= 105
1 <= heights[i] <= 109
