Questions & Step-by-Step Solutions
In which traversal method are nodes visited level by level?
Step 1: Understand what a tree is. A tree has a root node and branches that lead to other nodes.
Step 2: Know that traversal means visiting each node in the tree.
Step 3: Learn about different traversal methods. Common methods include pre-order, in-order, post-order, and level-order.
Step 4: Focus on level-order traversal. This method visits all nodes at the same level before moving to the next level.
Step 5: Start at the root node. Visit it first.
Step 6: Move to the next level and visit all nodes at that level from left to right.
Step 7: Continue this process until all levels of the tree have been visited.
Level-order Traversal – A method of tree traversal where nodes are visited level by level, starting from the root and moving down to each subsequent level.
