The easiest way to implement theinOrdertraversal algorithm in Java or any programming language is by using recursion. Since the binary tree is a recursive data structure, recursion is the natural choice for solving a tree-based problem. TheinOrder()method in theBinaryTreeclass implements the logi...

If I understand the exercise correctly, you would have to come up with formulas for how to calculate the label of the left and right child during each method of traversal, given the label of the current node and the depth. For example, during pre-order traversal, the ...

Vertical order traversal means that we find the different vertical lines in the binary tree, then print the nodes on these from left to right, the nodes on a vertical line are printed from to bottom. How do you vertically print a binary tree?
The recursion splits the problem into two halves at each level, and there are h levels in the binary tree. Therefore, the time complexity is O(n * h). 4.1.3 High Efficiency Indices as parameters The time complexity of constructing the binary tree using this method is O(n). The main ...
