You are given an integer array heights representing the heights of buildings in a row. The ocean is located to the right of all the buildings.

A building has an ocean view if every building to its right has a strictly smaller height.

Return an array containing the indices of all buildings that have an ocean view, sorted in increasing order. The indices are $0$ indexed.

Constraints:

• $1 \leq$ heights.length $\leq 10^5$

• $1 \leq$ heights[i] $\leq 10^9$
