Print all the cycles in an undirected graph in C++
In this problem, we are given an undirected graph and we have to print all the cycles that are formed in the graph. Undirected Graph is a graph that is connected together. All the edges of the unidirectional graph are bidirectional. It is also known as an undirected network. Cycle in a graph data structure is a graph in which all vertices form a cycle. Let's see an example to understand the problem better − Graph- Output- Cycle 1: 2 3 4 5 Cycle 2: 6 7 8 For this, we will make use of a few properties of ...
Read MoreMarket your Business for Free using Social Media Tools
A couple of days ago, I happened to read an article where I encountered this statement-“There is nothing called free lunch.” However, I do have a soul-searching question to all the business owners – Who doesn’t like free marketing tools?Small businesses and low budget startups know the value of every penny they invest.

Read MorePrint all the sum pairs which occur maximum number of times in C++
In this problem, we are given an array of n unique integers. And we have to find the sum of two integers of the array which has the maximum frequency. The problem has multiple solutions and you need to find them all.Input : array = { 1, 12, 5, 7, 9, 11} Output : 16 12Explanation − sum 16 and 12 occur two times.5 + 11 = 16 & 7 + 9 = 16 1 + 11 = 12 & 5 + 7 = 12Now to solve this problem, our approach to the problem is checking the occurrence every sum ...
Read MoreHuffman Trees in Data Structure
DefinitionHuffman coding provides codes to characters such that the length of the code depends on the relative frequency or weight of the corresponding character. Huffman codes are of variable-length, and without any prefix (that means no code is a prefix of any other). Any prefix-free binary code can be displayed or visualized as a binary tree with the encoded characters stored at the leaves.Huffman tree or Huffman coding tree defines as a full binary tree in which each leaf of the tree corresponds to a letter in the given alphabet.The Huffman tree is treated as the binary tree associated with ...
Read MoreDictionary Operations in Data Structure
A dictionary is defined as a general-purpose data structure for storing a group of objects. A dictionary is associated with a set of keys and each key has a single associated value. When presented with a key, the dictionary will simply return the associated value.For example, the results of a classroom test could be represented as a dictionary with student's names as keys and their scores as the values:results = {'Anik' : 75, 'Aftab' :80, 'James' : 85, 'Manisha': 77, 'Suhana' :87, 'Margaret': 82}Main operations of dictionariesDictionaries typically support so many operations −retrieve a value (based on language, attempting to ...
Read MoreBayes' Rule in Data Structure
A way to update our beliefs depended on the arrival of new, relevant pieces of evidence are provided by Bayes rule. For example, if we were trying to provide the probability that a given person has cancer, we would initially just conclude it is whatever percent of the population has cancer. However, given extra evidence such as the fact that the person is a smoker, we can update our probability, since the probability of having cancer is greater given that the person is a smoker. This allows us to utilize prior knowledge to improve our probability estimations.The rule is explained ...
Read MoreBoole's Inequality in Data Structure
In probability theory, according to Boole's inequality, also denoted as the union bound, for any finite or countable set of events, the probability that at least one of the events happens is no higher than the sum of the probabilities of the individual events.In mathematics, the probability theory is denoted as an important branch that studies about the probabilities of the random event. The probability is denoted as the measurement of chances of happening an event which is an outcome of an experiment.For Example − tossing a coin is denoted as an experiment and getting head or tail is denoted ...
