Queue follow FIFO as it is mentioned in the introduction. Five major operations: Enqueue(x): pushes x to the back of the queue. Dequeue(): pops an element from the front of the queue. isEmpty(): Finds whether the queue is empty or not. isFull(): Finds whether the queue is full or not. frontV...

Memory is efficiently organized in a circular queue as compared to linear queue. In Linear Queue: In Circular Queue: Remaining spaces can be used: Code for it to do the same: #include<stdio.h> #define MAX 10000 int front = -1; int rear = -1; int a[MAX]; bool isFull() { if...

Setup ActiveMQ Download a ActiveMQ distribution from activemq.apache.org and unpack it somewhere You can start the server immediately, running unsecured on localhost, using the script bin/activemq When it is running, you can access your local server's console on http://localhost:8161/admin/ Co...

First of all you should know that you can extend Android.Application class so you can access two important methods related with app lifecycle: OnCreate - Called when the application is starting, before any other application objects have been created (like MainActivity). OnTerminate - This...

Activity lifecycle is quite more complex. As you know Activity is single page in the Android app where user can perform interaction with it. On the diagram below you can see how Android Activity lifecycle looks like: As you can see there is specific flow of Activity lifecycle. In the mobile appl...

As you know you can have one activity but different fragments embedded in it. That is why fragment lifecycle is also important for developers. On the diagram below you can see how Android fragment lifecycle looks like: As described in the official Android documentation you should implement at le...

If you would like to get base project with methods described below you can download Xamarin.Android application template from my GitHub. You can find examples for: Application lifecycle methods Activity lifecycle methods Fragment lifecycle methods https://github.com/Daniel-Krzyczkowski/Xamar...

For example if the given tree is: Level order traversal will be 1 2 3 4 5 6 7 Printing node data level by level. Code: #include<iostream> #include<queue> #include<malloc.h> using namespace std; struct node{ int data; node *left; node *right; }; ...

You can pass parameters by Bundle: Bundle myBundle = new Bundle(); myBundle.putString(MY_KEY, myValue); Get the value in onCreateLoader: @Override public Loader<String> onCreateLoader(int id, final Bundle args) { final String myParam = args.getString(MY_KEY); ... }

You can create a Sequential model by passing a list of layer instances to the constructor: from keras.models import Sequential from keras.layers import Dense, Activation model = Sequential([ Dense(32, input_dim=784), Activation('relu'), Dense(10), Activation('softmax'), ]) ...

/* This is a simple query which can generate a sequence of numbers. The following example generates a sequence of numbers from 1..100 */ select level from dual connect by level <= 100; /*The above query is useful in various scenarios like generating a sequence of dates from a given date. The ...

This method allows non-implementation-specific code to be written and deployed across multiple jms platforms. Below basic example connects to activemq jms server and sends a message. import java.util.Properties; import javax.jms.JMSException; import javax.jms.Queue; import javax.jms.QueueConne...

When your device connects to a network, an intent is sent. Many apps don’t check for these intents, but to make your application work properly, you can listen to network change intents that will tell you when communication is possible. To check for network connectivity you can, for example, use the ...

/* This function returns TRUE if input is the letter "b" and false otherwise */ FUNCTION isTheLetterB RETURNS LOGICAL (INPUT pcString AS CHARACTER): IF pcString = "B" THEN RETURN TRUE. ELSE RETURN FALSE. END FUNCTION. /* Calling the function with "b&qu...

/* This will popup a message-box saying "HELLO WORLD" */ FUNCTION cat RETURNS CHARACTER ( c AS CHARACTER, d AS CHARACTER): RETURN c + " " + d. END. MESSAGE cat("HELLO", "WORLD") VIEW-AS ALERT-BOX.

A function can have multiple return statements and they can be placed in different parts of the actual function. They all need to return the same data type though. FUNCTION returning DATE ( dat AS DATE): IF dat < TODAY THEN DO: DISPLAY "<". RETURN dat - 200. ...
