The purpose of this laboratory is for you to demonstrate understanding of Binary Search Trees. The BinarySearchTree class definition is given as follows: class BinarySearchTree: def __init__(self, data, left=None, right=None): self.__data = data self._left = left self.__right = right def get_left(self): return self._left def get_right(self): return self._right def set_left(self, left): self. __left = left def set_right(self, right): self._right = right def set_data(self, data): self.__data = data def get_data(self): return self._data The print_tree() function is given as follows: def print_tree (tree, level): print(''* (level*4) + str(tree.get_data())) if tree.get_left() != None: print('(L)', end = '') print_tree(tree.get_left(), level + 1) if tree.get_right() != None: print('(R)', end = "") print_tree(tree.get_right(), level + 1) You will use the following binary search trees: 1 . tree1 = 27 14 35 10 19 31 42 . tree 2 = 10 14 . tree3 = 13 D P ( F K U tree4 = A E G NR Y An implementation of the BinarySearchTree ADT is shown in the answer box for this question. Extend the BinarySearch Tree class by adding the method search(self, value) which takes a value as a parameter. This method should search for the parameter value in the binary search tree. If the value is found, the method should return the found object, and None otherwise. Note: submit the entire class definition. For example: Test Result 9 None node = treel. search (9) if not isinstance(node, BinarySearchTree) : print('The search method must return an object of BinarySearchTree') print(node.get_data()) print(tree1. search(0)) tree = BinarySearchTree (15) print(tree. search(99)) print(tree. search(299)) None None Answer: (penalty regime: 0, 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 %) Reset answer 1 class BinarySearchTree: def _init__(self, data, left=None, right=None): self.__data data self.-_left = left self.__right = right def get_left(self): return self.__left def get_right(self): return self.__right def set_left(self, left): self. left = 'left def set_right(self, right): self.__right = right def set_data(self, data): self.__data data def get_data(self): return self.__data WISS WRFBorovorurawne
