Leetcode 614. Second Degree Follower
Given a directed "follows" graph, find the unique second-degree followers — users who follow one of a user's followers but do not directly follow that user (excluding the user themself). The core challenge is efficiently traversing depth‑2 neighbors and deduplicating results in a potentially large, cyclic graph.
