This is part of my own implementation of BST. The ugly part of this problem is that you have to know the space that your children occupies before you can print out yourself. Because you can have very big numbers like 217348746327642386478832541267836128736..., but also small numbers like 10, so if you have a parent-children relationship between these two, then it can potentially overlap with your other child. Therefore, we need to first go through the children, make sure we get how much space they are having, then we use that information to construct ourself. Show
Here's some examples of running this:
Another example:
How do I display a binary search tree in Python?To insert into a tree we use the same node class created above and add a insert class to it. The insert class compares the value of the node to the parent node and decides to add it as a left node or a right node. Finally the PrintTree class is used to print the tree.
How do I print a binary search tree?You start traversing from the root, then go to the left node, then you again go to the left node until you reach a leaf node. At that point in time, you print the value of the node or mark it as visited and move to the right subtree. Continue the same algorithm until all nodes of the binary tree are visited.
How do you print tree structure in Python?To print all nodes of a tree using depth-first search, only few lines are required:. def printTree(root, level=0):. print(" " * level, root.x). for child in root.children:. printTree(child, level + 1). #tree = Node(..., children=[Node(...., ...), Node(...,....)] ... . printTree(tree). How do I print BST in ascending order?Given an array that stores a complete Binary Search Tree, write a function that efficiently prints the given array in ascending order. Solution: Inorder traversal of BST prints it in ascending order. The only trick is to modify recursion termination condition in standard Inorder Tree Traversal.
