C++ 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?

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 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 ...
