Detailed explanation-1: -Breadth First Search (BFS) algorithm traverses a graph in a breadthward motion and uses a queue to remember to get the next vertex to start a search, when a dead end occurs in any iteration.
Detailed explanation-2: -Level Order Traversal Level order traversal follows BFS(Breadth-First Search) to visit/modify every node of the tree.
Detailed explanation-3: -Breadth First Search (BFS) BFS is a traversing algorithm where you should start traversing from a selected node (source or starting node) and traverse the graph layerwise thus exploring the neighbour nodes (nodes which are directly connected to source node). You must then move towards the next-level neighbour nodes.
Detailed explanation-4: -BFS(Breadth First Search) uses Queue data structure for finding the shortest path.
Detailed explanation-5: -A queue (FIFO-First in First Out) data structure is used by BFS. You mark any node in the graph as root and start traversing the data from it. BFS traverses all the nodes in the graph and keeps dropping them as completed. BFS visits an adjacent unvisited node, marks it as done, and inserts it into a queue.
