Q 101 - trees - inorder traversal solution

WebJun 8, 2024 · Given two integer arrays preorder and inorder where preorder is the preorder traversal of a binary tree and inorder is the inorder traversal of the same tree, construct and return the binary tree. Examples: Constraints: 1 <= preorder.length <= 3000 inorder.length == preorder.length -3000 <= preorder [i], inorder [i] <= 3000 WebGiven a binary tree, determine the traversal including Inorder,PreOrder and PostOrder. Perform an inorder traversal and preorder transversal of the following binary tree, and list the output in a single line. Examine a traversal of a binary tree. Let's say that visiting a node means to display the data in the node.
