The breadth-first traversal algorithm for a binary tree is a method used to visit all the nodes of the tree in a level-by-level manner. It starts at the root node and visits all the nodes at the current level before moving on to the next level.
Here is a step-by-step explanation of the breadth-first traversal algorithm:
1. Create an empty queue and enqueue the root node of the binary tree.
2. Start a loop until the queue is empty.
3. Dequeue a node from the front of the queue and visit it.
4. Enqueue the left child of the dequeued node if it exists.
5. Enqueue the right child of the dequeued node if it exists.
6. Repeat steps 3-5 until all nodes have been visited.
By following this algorithm, all the nodes of the binary tree will be visited in a breadth-first manner, starting from the root and moving level by level.
