The searching algorithms are used to search or find one or more than one element from a dataset. These type of algorithms are used to find elements from a specific data structures. Searching may be sequential or not. If the data in the dataset are random, then we need to use sequential searching. Otherwise we can use other different techniques to reduce the complexity. In this Section We are going to cover − Binary Search Exponential Search Interpolation Search Jump Search Linear Search Ternary Search
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
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 Glide example, we should know what is glide, Glide is an image processing library developed by muyangmin. Using glide library we can show image, decode images, cache images, animated gifs and many more.This example demonstrate about how to integrate glide in android.Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code in build.gradle(Module:app).apply plugin: 'com.android.application' android { compileSdkVersion 28 defaultConfig { applicationId "com.example.andy.myapplication" minSdkVersion 15 ...

In this section we will see some common mathematical problems and their possible way solve using different computational algorithms. We will see how to solve differential equations, integrations and some other complex mathematical problems. In this Section We are going to cover − Convert Infix to Postfix Expression Convert Infix to Prefix Expression Evaluate Postfix Expression Secant method to solve non-linear equation Trapezoidal Rule for definite integral Simpson's 1/3 Rule for definite integral Linear Regression Lagrange Interpolation Runge-Kutta 4th order rule for differential equation Lucky Numbers Decimal to Binary conversion Find LCM of two numbers Find ...

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 ...

These mysql_* functions are deprecated and other functions are available that gives better security and functionality. Note: As an alternative, use either _assoc or _row though. mysql_fetch_assoc The function returns an associative array of strings that corresponds to the fetched row, or FALSE if there are no more rows. The associativity array tells us about the key value pair, whereas the key tells about any column name and the value tells about the row value. Here we can map the column name as key and value as row. For example. Key is ID and value is corresponding name. ... Read More
Before getting into searchview example, we should know what is search view in android, search view is just like search box in HTML. we can search anything from particular list items.This example demonstrate about how to integrate search view in android.Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.Step 2 − Add the following code to res/layout/activity_main.xml. In the above code we are giving search view and listview because search view going to search element from ... Read More
We cant touch background thread to main thread directly so handler is going to collect all events which are available in main thread in a queue and posses this queue to looper class.In android Handler is mainly used to update the main thread from background thread or other than main thread. There are two methods are in handler.Post() − it going to post message from background thread to main thread using looper.sendmessage() − if you want to organize what you have sent to ui (message from background thread) or ui functions. you should use sendMessage().This example demonstrate about how to ...
