C++ Program to Emulate N Dice Roller
Emulating an n dice roller refers to rolling n number of dice simultaneously. In each roll, all the dice will return a different value from 1 to 6. In this article, we are having 'n' number of dices, our task is to emulate rolling n dices simultaneously. The approaches are mentioned below: Using Loop with rand() Function Using Recursion Using Loop with rand() Function In this approach, we have used the rand() function to generate a random value of dice in each roll. The srand() function with time() is ...
Read MoreC++ Program to Check the Connectivity of Undirected Graph Using BFS
The Breadth-First Search (BFS) algorithm is a graph traversal algorithm that starts at the tree root and explores all nodes at the present depth before moving to the nodes at the next level. In this article, we will discuss how to check the connectivity of a graph using BFS traversal algorithm. Understanding Connectivity of a Graph A graph is said to be connected if there is a path between every pair of vertices. To check connectivity of a graph, we will try to traverse all nodes using any traversal algorithm. After completing the traversal, if there is any ...
Read MoreWhat is the importance of a Cursor class in Java?
In this article, we will learn about the importance of the Cursor class in Java. Under the Swing toolkit, the Cursor class provides an improved user experience by providing graphical(visual) feedback. What is a Cursor class? A Cursor is a subclass of the Object class, and it can be defined as point or indicator on the screen. A Cursor is used to select the input from the system that the user operates with the mouse. The important methods of Cursor class are getDefaultCursor(), getName(), getPredefinedCursor(), getSystemCustomCursor(), and getType(). Syntax The following is the syntax: Cursor cursor = new Cursor(Type_of_Cursor); Different ...
Read MoreWhat should main() return in C and C++?
In C/C++, the main() function is used in the beginning of every program. This returns the program execution status in the operating system. Syntax Following is the syntax of the main() function using C/C++: int main(void); int main(int argc, char *argv[]); Example Below, the C/C++ example shows the usage of the main() return value. C C++ #include int main() { printf("Hello, C World!"); return 0; } Key Points of C Return 0: This is standard for successful execution Non-zero: It indicates error Implicit return: C99 allows omitting return #include int main() { std::cout
Read MoreCheck if all the 1s in a binary string are equidistant or not in C++
In this problem, we are given a binary string, and we have to check if all the 1s present in the binary string are at an equivalent distance from each other. Example 1 Input: binaryString = "10101010" Output: Yes Explanation The positions of 1s in the given string are 1, 3, 5, and 7.Here, the difference between consecutive 1s is 2 (as 7-5 equals 5-3 equals 3-1), so all 1s are at an equivalent distance from each other. Example 2 Input: binaryString = ...
Read MoreDifference between Tree Set and Hash Set in Java
In Java, HashSet and TreeSet both belong to the collection framework. HashSet is the implementation of the Set interface, whereas TreeSet implements a sorted set. TreeSet is backed by TreeMap while HashSet is backed by a HashMap. Difference Table The following are the key differences between HashSet and TreeSet : Sr. No. Key ...

Passing multiple props in a single event handler in ReactJS can be useful for situations where more than one value needs to be worked on based on some user input. In this article, we will discuss three different ways to pass props in a single event handler in ReactJS. Here is a list of approaches: Using Arrow Functions Using bind() Method Using Event Object Using Arrow Functions To pass multiple props in a single event handler, we will use the most popular approach i.e. ...
Read MoreJava program to compare two sets
The given task is to write Java programs that compare two sets and check if they are equal or not. Here, Set is an interface of the Java Collection Framework that extends the Collection interface and stores unique elements. Set depicts the features of a mathematical set. Hence, it allows all those operations that we can perform on a mathematical set, such as union, comparison, intersection, etc. Since Set is an interface, we can't use its functionalities directly. For this purpose, we need a TreeSet class that implements the Set Interface and can access its methods. How to Compare Two Sets in ...
