- Q1. Deep dive into java concepts. Max diameter of a tree in java.
- Ans.
Max diameter of a tree in Java is the longest path between any two nodes in a tree.
The diameter of a tree can be calculated by finding the longest path between any two nodes in the tree.
This can be done by finding the longest path from the root to a leaf node, and then finding the longest path from another leaf node to the root.
The sum of these two paths gives the diameter of the tree.
