Leetcode Problem 1245. Tree Diameter
Leetcode Solutions
Approach: Farthest Nodes via BFS
- Convert the edge list into an adjacency list to represent the tree as a graph.
- Perform BFS starting from an arbitrary node (e.g., node 0) to find the farthest node from it. Keep track of the visited nodes and the distance from the starting node.
- Perform BFS a second time starting from the farthest node found in step 2. Again, keep track of the visited nodes and the distance from the starting node.
- The maximum distance found in the second BFS is the diameter of the tree.
Approach: DFS (Depth-First Search)
