If you keep visited flags in the binary tree while traversing, the problem could be solved in a more direct manner. But we will not discuss this solution here, as it has already been discussed in Wikipedia’s article onTree Traversal. Here, we discuss a solution without using any visited ...
Given a binary search tree, print the elements in-order iteratively without using recursion.Note:Before you attempt this problem, you might want to try coding a pre-order traversal iterative solution first, because it is easier. On the other hand, coding a post-order iterative version is a ...

So I've been thinking about this, and although it seems like CS101 to transform a recursive algorithm into an iterative one, and example might be worth while. The natural one to attack would be the generic binary tree traversal iterator. So here goes!
// Iterative function to calculate the height of a given binary tree // by doing level order traversal on the tree intheight(Node*root) { // empty tree has a height of 0 if(root==nullptr){ return0; } // create an empty queue and enqueue the root node ...

Minimum Depth of Binary Tree by using Recursive Depth First Search and Iterative Breadth First Search Algorithms To find out the minimum depth of a binary tree, we can use the DFS (Depth First Search) Algorithm or Breadth First Search (BFS) Algorithm.
You have two choices, eitheradd the element at the heador at the tail, adding an element to the head is easy as it doesn't require a traversal till the end but if you want to create a list that contains elements in the order they are added then we need to add nodes at the end ...
Insertion Sort Selection Sort In every programming language, these methods can be implemented to arrange values. Answer and Explanation:1 Source code Here, the merge sort will be executed using the C++ language. It follows the divide and conquers algorithm in which the array is......
Breadth–first search (BFS)is a graph traversal algorithm that explores vertices in the order of their distance from the source vertex, where distance is the minimum length of a path from the source vertex to the node as evident from the above example. ...
