For a given character, say "ch", write a Java program to print its ASCII value. We can find the ASCII value of any character by assigning it to an integer value and printing that integer value. The term ASCII stands for American Standard Code for Information Interchange. There are 128 standard ASCII codes, each of which can be represented by a 7-digit binary number: 0000000 through 1111111. Extended ASCII adds an additional 128 characters that vary between computers, programs and fonts. Example Scenario: Input: character = s; Output: ascii_value = 115 Example 1 In this example, we are printing ... Read More
A Graph is a non-linear data structure made up of a group of vertices and edges. A vertex or node represent an object, and the connections between them are called edges. In this article, we will understand how to implement the graph data structure in Java. Algorithm Step 1: START Step 2: Create a class and its constructor to initialize graph. In this class, use LinkedList for creating adjacency list. Step 3: Define a method in the same class to add edges to the graph. ... Read More
Given a number of type integer, write a Java program to print its factorial. The factorial of a positive integer n is the product of all values from n to 1. For example, the factorial of 3 is (3 * 2 * 1 = 6). Let's understand the problem statement with examples − Example Scenario 1: Input: int n = 4; Output: res = 24 Calculation: 4! = 4 * 3 * 2 * 1 = 24 Example Scenario 2: Input: int n = 0; Output: res = 1 Factorial of 0 is always 1. Finding Factorial ... Read More
