Trees Traversals Please write a Java program to traverse a binary tree in in-order and pre-order, and to plot a binary tree into a 2-dimensional array. You may write many recursive methods for this project. You are not allowed to use any existing Java classes such as ArrayList or Vector or Tree. Please stop your program if the user enters 0 as the tree selection. Your program must run the following Test Case 1 plus two more test cases to...

PROBLEM 6: Suppose we insert keys below into an initially empty Vanilla binary search tree in the given order: 6, 9, 2, 1, 5, 7, 10, 8, 3, 4 (a) Draw the resulting binary search tree. (b) List the keys according to: A pre-order traversal An in-order traversal A post-order traversal (c) Now we perform some deletions using the “deletion by copying” strategy in which promoted keys are always drawn from a node’s right subtree (so that there is only...

Construct Tree Using Inorder and Preorder
Given Preorder and Inorder traversal of a binary tree, create
the binary tree associated with the traversals.You just need to
construct the tree and return the root.
Note: Assume binary tree contains only unique elements.
Input format :
Line 1 : n (Total number of nodes in binary tree)
Line 2 : Pre order traversal
Line 3 : Inorder Traversal
Output Format :
Elements are printed level wise, each level in new line...
