FAQ on Data Structure

Queue data structure The most suitable data structure for constructing a tree is usually a linked data structure. Specifically, a common choice is to use a linked list or an array of nodes, where each node represents a specific element or value within the tree. Each node typically contains references or pointers to its child … Read more

2k+1-1 where k >= 1 The maximum number of nodes in a binary tree of height k can be calculated using the formula: 2�+1−12k+1−1 This formula represents the maximum number of nodes that can exist in a binary tree of height �k. It derives from the fact that each level of a binary tree doubles … Read more

void in-order(struct treenode *tree) { if(tree != NULL) { in-order(tree→ left); printf(“%d”,tree→ root); in-order(tree→ right); } } Sure, here’s an example of C code to perform an in-order traversal on a binary tree: cCopy code #include <stdio.h> #include <stdlib.h> // Define the structure for a binary tree node struct TreeNode { int data; struct TreeNode … Read more

A binary Tree is a special type of generic tree in which, each node can have at most two children. Binary tree is generally partitioned into three disjoint subsets, i.e. the root of the node, left sub-tree and Right binary sub-tree. A binary tree is a hierarchical data structure in which each node has at … Read more

There are six types of tree given as follows. General Tree Forests Binary Tree Binary Search Tree Expression Tree Tournament Tree In a data structure interview, when asked to list the types of trees, you can mention several types based on their characteristics and organization. Here are some common types of trees: Binary Tree: A … Read more
