Task 1 Each node in a binary tree contains an integer value and two pointers to next-level nodes: “left” and “right”. Write a function that takes a pointer to a root of a tree and checks whether the tree is sorted. Task 2 There is a 3D point and a line segment (bounded 3D line) given by endpoints. (..)write a function that will compute the dista…
