Given age of a person and we have to check whether person is eligible for voting or not using Ternary operator. Trees are non-linear data structures representing nodes connected by edges. The properties that separates a binary search tree from a regular binary tree is The ternary search tree (TST) is a dictionary data structure specially crafted for the situation where the key are string. Here we will learn about the ternary tree, doubly linked list, and how to create a doubly linked list from a ternary tree. • (A)dd a word and its frequency to the dictionary. It is used to express a simple conditional expression concisely, usually in one line. It helps us to write conditional statements in Python in a single line. Similarly the ternary operator in python is used to return a value based on the result of a binary condition. The Ternary Search Trie helps avoid the unnecessary space needed by a traditional multi-way trie while still maintaining many of its advantages. The Ternary Operator came as an enhancement in the Python 2.5 version. I found that if I do the In-order traversal on the Ternary Search Tree(a type of Trie data structure) for a particular searched string then visiting order of nodes should be :- My take on your Ternary search tree: With added typing hints, implementing the __getitem__ and __setitem__ magic methods. In a Ternary Search Trie each node contains a character and three pointers. Binary search tree is a special binary tree that consist of 0, 1 or 2 child nodes and follows certain rules while inserting the value in the node. This can be accomplished by traversing the ternary tree in a pre-order fashion that is, root -> left the child -> middle child -> right child. The algorithm for constructing the binary tree from the ternary expression is: Pre-requisite: Ternary expression str The Binary search tree is a binary tree in which all the nodes follow the below mentioned properties.
