Find the diameter of a binary tree
WebThis link provides an algorithm for finding the diameter of an undirected tree using BFS/DFS. Summarizing: Run BFS on any node s in the graph, remembering the node u discovered last. Run BFS from u remembering the node v discovered last. d(u,v) is the diameter of the tree. Why does it work ? Page 2 of this provides a reasoning, but it is ...
