Create a function that takes an array that represent a Binary Tree and a value and return true if the value is in the tree and, false otherwise. Examples valueInTree (arr1, 5) true valueInTree (arr1, 9) → false valueInTree (arr2, 51) → false

Create a function that takes an array that represent a Binary Tree and a value and return true if the value is in the tree and, false otherwise. Examples valueInTree (arr1, 5) valueInTree (arr1, 9) valueInTree (arr2, 51) - true 1 false false

The level of a node in the tree is the number of nodes in the path from the root to the node (including itself). For example, the node 15 in the example tree above has a level of 2. Write a function prune-tree that will take a tree representation as well as an integer level. It will return a new tree containing only nodes that have level not exceeding level. The order of the nodes in the result list should be the same as the original order in the tree. You may assume that level is a non-negative integer. write the program in racket
