LeetCode 310 – Minimum Height Trees | Graph | Topological Sort | Leaf Removal | Java

In this video, we solve LeetCode 310: Minimum Height Trees using an efficient Graph + Topological BFS approach.
Instead of checking the height from every node (which would be slow), we use the leaf removal technique, similar to topological sorting, where we repeatedly remove leaf nodes until only the centroids remain.
These remaining nodes are the roots of Minimum Height Trees.
