Linked List The linked list is a linear data structure containing elements called nodes. Each node consists of two main components: data (payload of that node) and a pointer to the next node in the list. They are simple and efficient to use providing easy allocation and deallocation of memory. ... Read More

In today’s world with a large amount of data and interconnected systems, a vast amount of data is created and stored across various machines. One challenging challenge is to sort this data stored across multiple devices. Sorting being a fundamental operation in computations is used for optimal retrieval, search and ... Read More

In computer science, binary matrix holds a very strong position containing a lot of information as the data is depicted using 0’s and 1’s which is the language of computers. In binary matrix, unique row refers to a row that is not identical to any other row in the matrix. ... Read More

Given a scenario of a company where meetings are held during fixed time slots. These slots might be overlapping or distant. Thus, optimizing meeting efficiency is important in order to accommodate maximum meetings without any conflicts between schedules. In the problem given, we’ll be going through such an optimizing meeting ... Read More

In order to design efficient data structures for specific operations, the time and space complexity of the given operations for the data structure created is important. Looking into some basic operations and how they can be efficiently optimized − insert() − Inserts an element to the data structure Dynamic Arrays, Hash Tables, ... Read More

The N-ary tree is a tree data structure where each node can have a maximum of N children where N is a positive integer (N >= 0). N-ary trees are used in many applications like file systems, organizational charts and syntax trees in programming languages. Example of N-ary tree with ... Read More

Problems involving grids and matrices are mostly solved using either BFS or DFS traversal algorithms. Taking a look into the first one, Breadth First Traversal − BFS or Breadth First Traversal is an algorithm for searching a tree or a graph data structure. It starts at the root node and ...

Reducing an array to a single element by repeatedly removing element is done by the following criteria − Select indices i and j such that i < j and arr[i] < arr[j] and convert one of the two elements to 0. Problem Statement Given an array arr[] containing positive integers. ... Read More

Recurrence Relation − In mathematics, recurrence relation refers to an equation where the nth term of the sequence is equal to some combination of the previous terms. For a recurrence relation where each term equals the product of previous K terms, let’s define N and K along with an array ... Read More
