In Python, it is very easy to implement stack and queue data structures. Stack is called LIFO because Stack works on the principle of "Last-in, first-out" and Queue is called FIFO because Queue works on the principle of "First-in, first-out", and the inbuilt functions in Python make the code shorter and simple. The Queue module implements multi-producer, multi-consumer queues and It is especially useful in threaded programming when information must be exchanged safely between multiple threads. The Queue class in this module implements all the required locking semantics and it depends on the availability of thread support in Python. This ... Read More
A palindrome is a sequence that is same both forwards and backwards. The binary representation of a number is checked for being a palindrome but no leading 0’s are considered. An example of this is given as follows − Number = 5 Binary representation = 101 The binary representation of 5 is a palindrome as it is the same both forwards and backwards. A program that demonstrates this is given as follows. Example Live Demo public class Example { public static void main(String argc[]) { long num ... Read More
The intersection of the two arrays results in those elements that are contained in both of them. If an element is only in one of the arrays, it is not available in the intersection. An example of this is given as follows − Array 1 = 1 2 5 8 9 Array 2 = 2 4 5 9 Intersection = 2 5 9 A program that demonstrates the intersection of two sorted arrays in Java is given as follows. Example Live Demo public class Example { public static void main(String args[]) ... Read More
The GRUB (Grand Unified Bootloader) is a bootloader available from the GNU project. A bootloader is very important as it is impossible to start an operating system without it. It is the first program which starts when the program is switched on. The bootloader transfers the control to the operating system kernel. GRUB Features GRUB is the default bootloader for many of the Linux distributions. This is because it is better than many of the previous versions of the bootloaders. Some of its features are: GRUB supports LBA (Logical Block Addressing Mode) which puts the addressing conversion used ... Read More
The graph is a non-linear data-structure, which consists finite number of nodes and a set of edges which are used to connect a pair of nodes. The graphs are used to solve some real-time problems to represent network etc. In different social networks, the graphs are used. In this Section We are going to cover − Bi-Connected Graph Checking Breadth First Search (BFS) for a Graph Bridges in a Graph Check if a given graph is tree or not Connectivity in a directed graph Depth First Search (DFS) for a Graph Detect Cycle in a an Undirected Graph Detect ...

Before getting into the Navigation view example, we should know about navigation view. Navigation view is just like a sliding menu in HTML. Navigation view is extended by navigatoin drawer. Most of use cases of Navigation view is used to redirect different activities or show profile information.This example demonstrate about how to integrate NavigationView in ActionBarStep 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step2 − While creating project we should select Navigation drawer activity as shown belowAfter selecting navigation drawer activity click on ...

The System.out.format is used in Java to format output. Here, let’s say the following is our long. long val = 787890; To format, we have considered the following that justifies the output. System.out.format("%d%n", val); System.out.format("%9d%n", val); System.out.format("%+9d%n", val); System.out.format("%08d%n", val); System.out.format("%, 9d%n", val); The following is the complete example that displays the difference in output as well. Example Live Demo import java.util.Locale; public class Demo { public static void main(String []args) { long val = 787890; System.out.format("%d%n", val); ... Read More
