If the node is found, delete the node.Sample Solution: Python Code:# Definition: Binary tree node. class TreeNode(object): def __init__(self, x): self.val = x self.left = None self.right = None def delete_Node(root, key): # if root doesn't exist, just return it ...
def search(self, node, parent, data): if node is None: return False, node, parent if node.data == data: return True, node, parent if node.data > data: return self.search(node.lchild, node, data) else: return self.search(node.rchild, node, data) # 插入 def insert(self, data):...
root.right = self.__delete(root.right, right_min.key) elif root.left: root = root.left elif root.right: root = root.right else: root = None #python的GC会在没有引用指向对象的时候销毁对象 return root def find(self, key): node = self.__find(self.root, key) if not node: print '...
二叉搜索树(Binary Search Tree,BST),又称为二叉搜索树,二叉排序树,是具有下列性质的二叉树: 若它的左子树不空,则左子树上所有结点的值均小于它的根结点的值; 若它的右子树不空,则右子树上所有结点的值均大于它的根结点的值; 它的左、右子树也分别为二叉排序树。
