Binary Search Tree is a node-based binary tree data structure which has the following properties: The left subtree of a node contains only nodes with keys lesser than the node's key. The right subtree of a node contains only nodes with keys greater than the node's key. The left and right subtree each must also be a binary search tree.

It looks like You are dealing with an unweighted graph. We interpret this as every edge has a weight of 1. In this case, once You have associated a distance to the root node with every node of the graph (the breadth-first traversal), it becomes trivial to reconstruct the shortest path from any node, and even detect if there are multiple ones.

Here we can execute two searches, ready from vertex 0 and other from vertex 14. When both forward the backward search meet at vertex 7, we know that we have found one path off node 0 to 14 and search capacity be terminate now. Were can clearly see that we have success avoided non-essential exploration. Presentation on Breadth First Search (BFS)Input: BFS (Breadth-First Search) is a graph traversal technique where a node and its neighbours are visited first and then the neighbours of neighbours. In simple terms, it traverses level-wise from the source. First, it traverses level 1 nodes (direct neighbours of source node) and then level 2 nodes (neighbours of source node) and so on.For a directed graph the whole matrix should be considered. Step1: maintain an array of Boolean values for saving whether a node is visited or not. Step2: implement a queue. Step3: start with any element and push it into the queue and Mark it as visited.
The steps involved in the BFS algorithm to explore a graph are given as follows -. Step 1: SET STATUS = 1 (ready state) for each node in G. Step 2: Enqueue the starting node A and set its STATUS = 2 (waiting state) Step 3: Repeat Steps 4 and 5 until QUEUE is empty. Step 4: Dequeue a node N. Process it and set its STATUS = 3 (processed state).
