What traversal method would you use to get the nodes of a binary tree in sorted order?
Step 1: Understand what a binary tree is. A binary tree is a structure where each node has at most two children, referred to as the left child and the right child.
Step 2: Know what a binary search tree (BST) is. A BST 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: Learn about traversal methods. Traversal methods are ways to visit all the nodes in a tree. Common methods include in-order, pre-order, and post-order.
Step 4: Focus on in-order traversal. In in-order traversal, you visit the left child first, then the parent node, and finally the right child.
Step 5: Apply in-order traversal to a BST. When you perform in-order traversal on a BST, you will visit the nodes in ascending order (sorted order).
Step 6: Conclude that in-order traversal is the correct method to get the nodes of a binary tree in sorted order.
