We can use the following technique to find the cheapest way to multiply X or right−rotate its digits from 1 to N. To monitor the initial lowest cost, create a cost variable. Check to see if N is evenly divided by X at each stage as you progress from N to 1. If so, divide N by X to update it and carry on with the process. Rotate N's digits to the right to increase its value if it is not divisible by X. Increase the cost variable in this situation. The ultimate cost variable value will be the least ... Read More
In this topic, we seek the relationally constrained lexicographically minimal permutation of numbers from 1 to N. The relation describes the relative order of certain of the permutation's components. We ensure that the resulting permutation is the least possible when comparing lexicographically by carefully organising the numbers based on this relation. In order to achieve the lowest feasible arrangement of the numbers, the best sequence must be found that both meets the relation restrictions and does so. To efficiently produce the intended outcome, the procedure entails thorough analysis and element selection. Methods Used Greedy Approach Backtracking Greedy Approach ... Read More
Diverse domains, including CS, social networks, and logistics, use directed graphs, also known as digraphs. Arrows indicating the direction of links serve to depict the interconnections between the various components. They have the ability to represent intricate connections, handle data quickly, and facilitate pathfinding algorithms. Their drawbacks, however, include the potential for analysis complexity, the challenge of visualising vast graphs, and the requirement for cautious treatment of cyclic structures. Despite these drawbacks, directed graphs continue to be fundamental tools for comprehending, evaluating, and enhancing interconnected systems in a variety of real−world contexts. Methods Used Topological Sorting Strongly Connected Components ... Read More
Graphs are used in different disciplines. They are utilised in biology to represent gene interactions, in transportation for route optimisation, and in social networks for user connection analysis. The visual representation of intricate relationships and the capacity to see patterns and trends are two benefits of graphs. However, dealing with large datasets can make graphs bulky and difficult to understand. Additionally, creating graphs can take time and necessitate knowledge. Despite these drawbacks, graphs continue to be an effective tool for data analysis and decision−making across a range of disciplines. Methods Used Set Representation Linked Representation Sequential Representaion Set ... Read More
The number of nodes that may be reached from any particular node in a graph is called as the count of nodes accessible from all other nodes in the graph. It shows the degree of reachability and connectivity inside the graph. We start at each node and investigate all accessible routes to other nodes in order to get this count.The nodes we can access are recorded as we move across the graph. The count of reachable nodes in the graph includes all nodes that can be reached. This is vital for understanding network relationships and information flow efficiency. Methods Used ... Read More
Introduction Today, the only way to save our planet is to start getting into the habit of recycling, reusing, and reducing. Companies as well as individuals have to reduce their carbon footprint. Waste management is crucial to learning as well as the solution to many of our problems. Companies have to come up with a circular economic system to strengthen their hold on the market. PHOOL is one such company that is high on sustainability, the Go Green approach, and the circular economy model. In this article, we will dive deep into the birth and growth trajectory of PHOOL so ... Read More
Clients can store, direct, and recover information from data sets utilizing programming known as a data set administration framework (DBMS). DBMS languages and interfaces, an essential component of a DBMS, enable user interaction with the database system. Data Definition Language is known as DDL in SQL. It is a portion of SQL (Structured Query Language) that is used to specify and control a database's structure. Database objects like tables, indexes, views, and constraints are created, modified, and deleted using DDL commands. DDL Commands There are several DDL commands, such as − CREATE − The create command is used to ... Read More
Clients can store, direct, and recover information from data sets utilizing programming known as a data set administration framework (DBMS). DBMS languages and interfaces, an essential component of a DBMS, enable user interaction with the database system. Data Control Language is referred to as DCL in SQL. It is a part of the SQL (Structured Query Language) subset that deals with rights and authorization for database objects. To give or revoke rights, manage user access, and regulate the security features of a database system, DCL statements are utilized. DCL Commands There are several DCL commands, such as − ...

In this problem, we have given the persona names and the number of taller people standing in front of that people. We can sort the position of the people according to the number of taller people standing in front of any person. After that, we update the position of each person according to the nums[] array value to get the original queue. Problem statement − We have given an array persons[] and nums[]. The persons[] array contains the person's name, and the nums[] array contains the number of taller people standing in front of each person. This queue is shuffled, ... Read More
In this problem, we will color the minimum nodes of the graph such that each node of the graph has a colored node at the maximum distance 1. The simple logic to minimize the count of the colored node is that either color the nodes which are at an odd distance or color the nodes at an even distance. So, we can color the alternative node, and for each node, we can have a colored node at most distance 1. Problem statement − We have given a graph containing N nodes and E edges. It is given that we can ... Read More
