WebImplementation steps: BFS traversal using queue Step 1: We create an empty queue called treeQueue and initialize it with the root node. Step 2: We then run a loop until the treeQueue is empty. Inside the loop, we declare a variable called currNode to keep track of the current node during the traversal. WebAs the name BFS suggests, you are required to traverse the graph breadthwise as follows: First move horizontally and visit all the nodes of the current layer. Move to the next layer.
