for inorder and level order tranvese, we needs to use a cur pointer on root but for pre and post order, we only needs to push the root. Core statement: while statement: preorder: while stack is not empty: pop() and added cur.val, stack.pop(cur.right) stack.pop(cur.left) postord...

The program creates a binary tree for breadth-first traversal.But i'm trying to use Pre-Order, In-Order, Post-Order Traversal and actually i can't do that. The output of the program is not what i expected. I think i should change the preorder, inorder or postorder functions but i ...
In each recursive call, theindex()function is used to find the index of the root value in the inorder traversal list. This function has a time complexity of O(n) in the worst case, where n is the number of elements in the list. Since the recursive calls are made for each node in ...

Though these are not the only way to traverse the tree, you can also use a breadth-first traversal algorithm like level order traversal (see Data Structures and Algorithms: Deep Dive Using Java), which traverses all nodes of a level before moving on to a new level. If you are preparing...
