Which 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 data structure where each node has at most two children, referred to as the left child and the right child.
Step 2: Learn about tree traversal methods. Tree traversal is the process of visiting all the nodes in a tree in a specific order.
Step 3: Identify the different types of traversal methods. The common methods are pre-order, in-order, and post-order.
Step 4: Focus on in-order traversal. In in-order traversal, you visit the left child first, then the current node, and finally the right child.
Step 5: Realize that in-order traversal of a binary search tree (BST) will give you the nodes in sorted order. This is because, in a BST, the left child is always less than the parent node, and the right child is always greater.
Step 6: Conclude that to get the nodes of a binary tree in sorted order, you should use in-order traversal.
