Questions & Step-by-Step Solutions
What is the result of a level-order traversal of the following binary tree: 1, 2, 3, 4, 5?
Step 1: Understand what a binary tree is. A binary tree is a structure where each node has at most two children.
Step 2: Visualize the binary tree with the given values: 1 is the root, 2 is the left child of 1, 3 is the right child of 1, 4 is the left child of 2, and 5 is the right child of 2.
Step 3: The binary tree looks like this:
1
/ \
2 3
/ \
4 5
Step 4: Level-order traversal means visiting nodes level by level, starting from the root.
Step 5: Start at the root (level 0): visit node 1.
Step 6: Move to the next level (level 1): visit nodes 2 and 3 from left to right.
Step 7: Move to the next level (level 2): visit nodes 4 and 5 from left to right.
Step 8: Combine the visited nodes in the order they were visited: 1, 2, 3, 4, 5.
