Technical Interview: Part 1 (Q&A): Tree - Pre Order Traversal of a binary tree (JAVA)

In this video we will see how to do a pre order traversal for a binary tree. # Given a binary tree, return the pre order traversal of its nodes' values. # Step by step instructions showing how to do pre-order tree traversal on a binary tree. # Uses of Preorder Preorder traversal is used to create a copy of the tree. Preorder traversal is also used to get prefix expression on of an expression tree. Input : 1 / \ 2 3 /. \ / \ 4. 5 6. 7 Output= Preorder: 1 2 4 5 3 6 7 ► Code of pre order traversing: https://bit.ly/2CMGeVX ► Buy me a Coffee: https://www.buymeacoffee.com/techanindya To understand how a solve interview questions on tree, please refer these following videos: [IMPORTANT] ►Complete List of interview questions that you need to prepare: https://bit.ly/34HXbMI ► Complete Playlist: (Part 1): - Pre Order Traversal: /watch/gtrMuyHQkjIQM (Part 2): - Level Order Traversal: /watch/wPry2X6wsSPwy (Part 3): - Print Left / Right View of a Binary Tree: /watch/wqXiXJoRVJkRi #technicalinterview #codinginterview #crackingthetechnicalinterview ►Additional Tags: pre order traversal binary tree, pre order traversal binary tree iterative, preorder postorder inorder tree traversal, pre order traversal binary tree python, pre order traversal binary tree algorithm, pre order traversal binary tree java, pre order traversal binary tree recursion, postorder to preorder traversal example, pre order traversal binary tree code, pre order traversal in binary tree, preorder traversal in bst, preorder postorder inorder binary tree, preorder traversal tree, pre order traversal of tree, pre-order traversal of binary tree, pre order traversal of binary tree, preorder postorder inorder, pre order post order traversal, pre order traversal online, preorder postorder inorder tree, preorder postorder inorder traversal, pre order postorder and inorder traversal, inorder traversal to preorder traversal, pre order traversal, pre order traversal binary tree program, preorder postorder inorder questions, pre order traversal binary tree without recursion, pre order traversal binary search tree, pre order traversal of a tree, preorder to inorder traversal, post order traversal to preorder traversal example, pre-order tree traversal in 3 minutes
