Read MoreC++ Program to Implement Graham Scan Algorithm to Find the Convex Hull
A convex hull is the smallest convex polygon with maximum area and minimum perimeter that encloses all the given points in a 2D plane. In this article, we will learn how to write C++ program to implement Graham Scan Algorithm to find convex hull. The objective of this problem is to take a set of x and y coordinates of a 2d plane as input, and display coordinate point from the set which are part of convex hull. // Input Set of points: {0, 0}, {1, 1}, {2, 2}, {2, 0}, {1, 2}, {0, 2} // Output Boundary ...

Before getting into the example, we should know what ConcurrentLinkedDeque is, it is unbounded deque based on linked nodes. Multiple threads can access deque elements with safety.This example demonstrates about How to use size() in android ConcurrentLinkedDequeStep 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 have taken a text view to show ConcurrentLinkedDeque elements.Step 3 − Add the following code to src/MainActivity.javapackage com.example.myapplication; import android.os.Build; import android.os.Bundle; ...
Read MoreTop-level script environment in Python (__main__)
A module object is characterized by various attributes. Attribute names are prefixed and post-fixed by double underscore __. The most important attribute of module is __name__. When Python is running as a top level executable code, i.e. when read from standard input, a script, or from an interactive prompt the __name__ attribute is set to '__main__'.>>> __name__ '__main__'From within a script also, we find a value of __name__ attribute is set to '__main__'. Execute the following script.'module docstring' print ('name of module:', __name__)Outputname of module: __main__However, for an imported module this attribute is set to name of the Python script. ...
Read MoreHow to determine device type (iPhone, iPod Touch) with Swift?
When working on iOS applications, we sometimes need to know the device on which application is installed, and provide custom features depending on the device in use. For example, we want to provide some features on iPhone X but not on iPhone 7. In this article we’ll learn how to find the iOS device being used, using an iOS Application.Let’s go through some terms that will be required for achieving the desired results, utsname − this is a structure located in Darwin module of iOSuname − uname is a function that takes utsname as an input and returns Int32 as ...
Read MoreHow to determine the current iPhone model information?
iOS Provides a UIDevice class which has all the information about your iPhone that does not violate any privacy laws Apple has.Using the UIDevice we can access information like −UIDevice.current.localizedModel − this returns the localized version of modelUIDevice.current.model − this returns model of current device, e.g. @"iPhone", @"iPod touch"UIDevice.current.name − this returns the current name of the device in use, e.g. "My iPhone"UIDevice.current.systemName − this returns the system name e.g. @"iOS"UIDevice.current.systemVersion − this returns the system version e.g. @"4.0"UIDevice.current.batteryLevel − this returns the battery level, if it is between 0 to 1, it will return the value otherwise if the ...

For example if you want to open a SMS from your app, it is possible using the registered URL Scheme.Some of the applications that can be opened with URL schemes and how to open them are ...
Read MoreCorona vs. Phonegap vs. Titanium
In this article we’ll learn about Corona, PhoneGap and Titanium, though all these technologies are different, the common thing between these is that they all are cross platform. i.e they can be used to write program once and then run that on multiple platforms like iPhones and android devices.Corona − Corona is a free and open source SDK (Software development kit), developed by corona Labs roughly 10 years ago in 2009. Corona is mainly for developing 2D mobile applications for most of the platforms including iOS, Android, Desktop/ Windows Applications. Corona is based on top of C++ and openGL to ...
