Question: Given a tree T=(V,E) compute its diameter, i.e. the longest path between two vertices. Do Breadth First Search(BFS) at a node s, find the farthest

Given a tree T=(V,E) compute its diameter, i.e. the longest path between two vertices. Do Breadth First Search(BFS) at a node s, find the farthest from s to get a vertex, say t. Then do Breadth First Search(BFS) to from t to find the farthest from t. Prove this gives diameter of tree. Diameter of a tree is the longest path in the tree.
