Two independent tasks are given. For each function, the example input is a Python literal matching its signature, usually a one-element tuple containing the primary argument. Outputs must be deterministic and exact. Task 1: Binary Search Tree Reconstruction You are given preorder, a list of distinct integers. This list is a valid preorder traversal of a binary search tree. Recover the tree and return its root. Use this nested representation for every node: [value,…
