Diameter of a graph and tree
Why there is a difference between diameter of a graph and tree? Diameter of a tree as i have read is the maximum path between two vertices(number of edges between two vertices) But for tree it says number of nodes on the longest path. But tree is a graph so why cant i find the diameter of tree in similar way?
