The Lighthouse Sightline

You are observing a row of lighthouses of various heights. Each lighthouse emits a horizontal beam of light to the right. A beam continues until it hits a lighthouse that is strictly taller than the originating one. For each lighthouse, determine the 0-indexed position of the lighthouse that stops its beam. If the beam never hits a taller lighthouse, output -1. Input Format: A single line containing space-separated integers representing lighthouse heights. Output Format: A single line containing space-separated integers representing the stopping indices. Example: Input: 4 2 5 3 Output: 2 2 -1 -1
