Data Structure and Algorithms

Data Structure and Algorithms are the building blocks of computer programming. A well-defined data structure helps us in keeping our data organized. Some of the commonly used data structures are List, Queue, Stack, Tree etc.

The algorithms provide different ways to achieve a task on these data structures. Some of the common algorithms are in the area of sorting and searching elements in the data structure.

Binary Search Tree (BST) – Search Insert and Remove

In this tutorial, we’ll be discussing the Binary Search Tree Data Structure. We’ll be implementing the functions to search, insert and remove values from a Binary Search Tree. We’ll implement these operations recursively as well….

Level Order Traversal or Breadth First Traversal of a Tree

In this tutorial, we’ll be discussing what’s Level Order Traversal. Also, we’ll be printing each level of the tree. We’ll use the two major approaches – Recursive and Iterative and see what’s the difference in….

Linked List Loop Detection – Floyd’s Cycle-Finding Algorithm

In this tutorial, we’ll be discussing a very popular algorithm which is used to detect whether a LinkedList has loops. It’s called Floyd’s Cycle-Finding Algorithm. LinkedList Loop Detection A loop exists in a LinkedList when….

Height of a Tree Data Structure

In this tutorial, we’ll be discussing Binary Trees. We’ll see how to calculate the height of a tree data structure recursively as well as iteratively. Binary Trees Binary Trees are a data structure in which….

Reverse a Linked List

Reversing a Linked List is an interesting problem in data structure and algorithms. In this tutorial, we’ll be discussing the various algorithms to reverse a Linked List and then implement them using Java. Reverse a….
