Related Topics Data Structure Question 228 What is a graph and what are its components (e.g. vertices, edges, weighted/unweighted)? Answer A graph is a collection of nodes, called vertices, and the connections between them, called edges. In computer science and mathematics, graphs are often used to represent networks, relationships, and dependencies. A graph can be […]
Related Topics Data Structure Question 220 What is the difference between a heap and a priority queue? Answer A heap and a priority queue are related data structures, but they have some important differences: A heap is a data structure that satisfies the heap property, which is a partial order property that states that for
Related Topics Data Structure Question 213 What is a heap and what are its characteristics? Answer A heap is a special kind of binary tree-based data structure that satisfies the heap property. The heap property can be either of two types: Max-Heap property: In a max-heap, the value of each node is greater than or
Related Topics Data Structure Question 205 Implement a binary tree that supports insert, search and delete operations in logarithmic time? Answer Yes, it is possible to implement a binary tree that supports insert, search and delete operations in logarithmic time. One way to achieve this is by using a self-balancing binary search tree like AVL
Related Topics Data Structure Question 198 What is a binary tree and what are its components (e.g. root node, left child, right child)? Answer A binary tree is a tree data structure in which each node has at most two children, which are referred to as the left child and the right child. The first
Related Topics Data Structure Question 191 What is the height of a tree and why is it important? Answer The height of a tree is the length of the longest path from the root to any leaf node in the tree. It is important because it affects the efficiency of many operations on the tree.
Related Topics Data Structure Question 184 What is a tree and what are its components? Answer In computer science, a tree is a non-linear data structure that consists of nodes connected by edges or branches. It is a hierarchical structure that is used to represent relationships between different elements in a set. A tree consists
Related Topics Data Structure Question 178 What are some common operations that can be performed on a queue? Answer Some common operations that can be performed on a queue include: Enqueue: Add an element to the back (tail) of the queue. Dequeue: Remove the element from the front (head) of the queue. Peek: Get the
Related Topics Data Structure Question 170 What is a queue and what are its characteristics? Answer A queue is a linear data structure that represents a collection of elements in a specific order in which the elements can be inserted and removed. It follows the First-In-First-Out (FIFO) principle, meaning that the first element inserted into
Related Topics Data Structure Question 163 What is the difference between a stack and a heap? Answer In computing, the terms “stack” and “heap” refer to two different regions of memory that are used for different purposes: Stack: The stack is a region of memory that is used for local variables and function call frames.
