Which binary tree traversal is best suited for generating a sorted list of elements?
Step 1: Understand what a binary tree is. A binary tree is a data structure where each node has at most two children, referred to as the left child and the right child.
Step 2: Learn about binary search trees (BST). A binary search tree is a special type of binary tree where the left child is less than the parent node, and the right child is greater than the parent node.
Step 3: Know what tree traversal means. Tree traversal is the process of visiting all the nodes in a tree in a specific order.
Step 4: Identify the types of tree traversal. The common types are in-order, pre-order, and post-order traversal.
Step 5: Focus on in-order traversal. In in-order traversal, you visit the left child, then the parent node, and finally the right child.
Step 6: Apply in-order traversal to a binary search tree. When you perform in-order traversal on a BST, you will visit the nodes in ascending order.
Step 7: Conclude that in-order traversal is best for generating a sorted list of elements from a binary search tree.
