What is the level-order traversal of a binary tree?

What is the level-order traversal of a binary tree?

Step 1: Understand that a binary tree is a structure made up of nodes, where each node can have up to two children (left and right).
Step 2: Level-order traversal means visiting each level of the tree one at a time.
Step 3: Start at the top level (the root node) and visit it first.
Step 4: Move to the next level down and visit all the nodes from left to right.
Step 5: Continue this process, moving down each level and visiting all nodes from left to right until you reach the bottom of the tree.
