What is the diameter of a tree?

A tree is a widely used data structure in the world of programming. This structure, as its name suggests, has branches and subdivisions. Each element in the tree is called a node.

N-ary trees are the trees in which each node has more than two child nodes. The diameter of an N-ary tree is basically the number of nodes on the longest path.The path must include the two leaf nodes. The illustration below shows a tree with a diameter of six.
