In the field of computer programming, finding the count of numbers between a given range that are coprime with a specific number can be a common task. Coprime numbers, also known as relatively prime numbers, are those that have no common factors other than 1. In this piece, we shall delve into finding the coprime numbers count between two given integers, L and R when referring to a particular number P, through the aid of C++ language. Syntax We'll commence by outlining the syntax of the approach we will be utilizing in the succeeding code examples − int countCoprimes(int ... Read More
In the realm of computer science and programming, discovering effective algorithms for resolving issues is highly significant. An intriguing issue is identifying the smallest possible quantity of maneuvers necessary to convert a string into a palindrome by increasing all characters within substrings. This write-up delves into two methodologies to handle this concern utilizing the C++ programming language. Syntax Before diving into the approaches, let's define the syntax of the function we will be using − int minMovesToMakePalindrome(string str); Algorithm Our objective is to minimize move count in converting strings into palindromes—a problem which our algorithm approaches with these ...

In this problem we have given a string ‘str’, integer K, and integer X. That string ‘str’ contains only integers in the range between 1 to 9. We have to perform an operation over the string exactly X times. Operation is that every time we have to replace a character of string by itself its frequency times. Here the frequency means the number or the value of the character of the string. Our task is to return the kth character after doing a given operation exactly X times. Sample Examples Input 1: str = “1231”, K = 5, X = ... Read More
Good problem-solving in computer science heavily relies on efficient algorithms like the Greedy-Best First Search (GBFS). GBFS has already established credibility as an optimal solution method for pathfinding or optimization issues. Therefore, we're discussing GBFS thoroughly in this article while exploring its implementation approach using C++. Syntax void greedyBestFirstSearch(Graph graph, Node startNode, Node goalNode); Algorithm The Greedy Best-First Search algorithm aims to find the path from a given start node to a goal node in a graph. Here are the general steps of the algorithm − Initialize an empty priority queue. Enqueue the start node into the priority ... Read More
Convert string means we have to make the same as a given string on the basis of a given condition. In this problem, we have given an array of strings ‘arr’ and string ‘T’ of size ‘M’. our task is to check if is it possible to make all the string present in an array as same as the given string T by removing any character from a string of an array ( arr[i] ) and inserting that character into any index of another string of the array ( arr[j] ). We can do this any number of times. If ... Read More
Efficiency and accuracy are often essential when solving complex problems in programming. One particular challenge involves appropriately identifying whether the maximum sum of N dice visible faces equals or surpasses X.

Furthermore, we will provide two real, full executable code examples based on the approaches mentioned. By the end, you will have a clear understanding of how to check if the maximum sum of visible faces of N dice is at least X in C++. Syntax Before diving into ... Read More
In graph theory, finding the minimum spanning tree (MST) of a connected weighted graph is a common problem. The MST is a subset of the graph's edges that connects all the vertices while minimizing the total edge weight. One efficient algorithm to solve this problem is Boruvka's algorithm. Syntax struct Edge { int src, dest, weight; }; // Define the structure to represent a subset for union-find struct Subset { int parent, rank; }; Algorithm Now, let's outline the steps involved in Boruvka's algorithm for finding the minimum spanning tree − ...
