Why did NASA need to observationally confirm whether DART successfully redirected Dimorphos? @ChrisChambers Thanks for the reply. Similarly, height of a single node will be considered as 1. Once the tree is created successfully, we have printed the tree level-wise, which means the nodes in one level are printed and then the nodes in the next level are printed until all the nodes in the tree are exhausted. We have also implemented a sample java code for all of these types of trees like General Tree, Binary Tree, Binary Search Tree, AVL Tree, Red-Black Tree, and N-ary Tree.
