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 WebFor traversing a (non-empty) binary tree in a preorder fashion, we must do these three things for every node n starting from the tree’s root: (N) Process n itself. (L) Recursively traverse its left subtree. When this step is finished, we are back at n again. (R) Recursively traverse its right subtree.
