which view of binary tree showed nodes at each level
Question
which view of binary tree showed nodes at each level
Solution
The view of a binary tree that shows nodes at each level is called the "Level Order Traversal" or "Breadth-First Search" (BFS) view. Here's how you can obtain it:
- Start from the root node.
- Create a queue and add the root node to it.
- While the queue is not empty, perform the following steps:
- Dequeue a node from the queue.
- Print the node's data.
- If the dequeued node has a left child, add it to the queue.
- If the dequeued node has a right child, add it to the queue.
- Repeat step 3 until the queue is empty.
This way, you're visiting each level of the binary tree from left to right, which gives you the level order traversal view.
