Connect nodes at same level (set next sibling)-binary tree DFS/example

Given a binary tree, we need to connect the nodes lying at same level. We have already discussed about the tree traversal using breadth first search algorithm, where we are printing the nodes level by level. By the end of this article we will achieve the same result using next sibling reference. In binary tree, we generally have following information.

Check given binary trees are Isomorphic in java (recursive / examples)

We are given two binary tree, we need to find out whether one binary tree is Isomorphic of other binary tree. What is Isomorphic meaning? As per English dictionary meaning is “being of identical or similar form, shape, or structure”. By apply above definition to our problem statement, If given binary have identical or similar form or shape or structure to another binary tree, we can say that trees are isomorphic.
