WebMar 28, 2024 · Inorder traversal is defined as a type of tree traversal technique which follows the Left-Root-Right pattern, such that: The left subtree is traversed first Then the root node for that subtree is traversed Finally, the right subtree is traversed Inorder traversal Algorithm for Inorder Traversal of Binary Tree

WebBroadly, we can understand divide-and-conquer approach in a three-step process. Divide/Break This step involves breaking the problem into smaller sub-problems. Sub-problems should represent a part of the original problem. This step generally takes a recursive approach to divide the problem until no sub-problem is further divisible. WebTree traversal is a process of visiting all the nodes of a tree. Since root (head) is the first node and all nodes are connected via edges (or links) we always start with that node. There are three ways which we use to traverse a tree − Inorder Traversal: Algorithm: Step 1.
