Given a Binary Tree and a positive integer k, print all nodes that are distance k from a leaf node.
Here the meaning of distance k from a leaf means k levels higher than a
tree
Check Binary Tree is Binary Search Tree or not
To search Binary Search Tree
First lets understand characteristics of BST
• The left subtree of a node contains only nodes with keys less than the node’s key.
• The right subtree of a node

Inorder and Preorder traversals of a Binary Tree given. Output the Postorder traversal of it.
Generate Postorder traversal of Tree from Inorder and Preorder traversal of tree without generating Tree.
Input:
In-order traversal in[] = {4, 2, 5, 1, 3, 6}
Pre-order traversal pre[] = {1, 2, 4, 5, 3, Spanning Tree
In the mathematical field of graph theory, a spanning tree T of a connected, undirected graph G is a tree that includes all of the vertices and some or all of the edges of G.
BFS (Breath First Search)
In graph theory, breadth-first search (BFS) is a strategy for searching in a graph when search is limited to essentially two operations: (a) visit and inspect a node of a graph; (b) gain access to
DFS (Depth First Search)
Depth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. One starts at the root (selecting some arbitrary node as the root in the case of a graph) and explores
