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.

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...
For example
if the input is:
Output should be false:
As 4 in the left sub-tree is greater than the root value(3)
If the input is:
Output should be true
Linked list representation is more efficient in terms of memory managerment.
Code to show enqueue and deque in a Queue using Linklist in O(1) time.
#include<stdio.h>
#include<malloc.h>
struct node{
int data;
node* next;
};
node* front = NULL;
node* rear = NULL;

A Vector3 structure can be created in several ways. Vector3 is a struct, and as such, will typically need to be instantiated before use.
Constructors
There are three built in constructors for instantiating a Vector3.
ConstructorResultnew Vector3()Creates a Vector3 structure with co-ordinates of...
The Vector3 structure contains some static functions that can provide utility when we wish to apply movement to the Vector3.
Lerp and LerpUnclamped
The lerp functions provide movement between two co-ordinates based off a provided fraction. Where Lerp will only permit movement between the two co-or...
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/

Android Apps are written in Java. The Android SDK tools compile the code, data and resource files into an APK (Android package). Generally, one APK file contains all the content of the app.
Each app runs on its own virtual machine(VM) so that app can run isolated from other apps. Android system wor...
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

Consider the Binary Tree:
Pre-order traversal(root) is traversing the node then left sub-tree of the node and then the right sub-tree of the node.
So the pre-order traversal of above tree will be:
1 2 4 5 3 6 7
In-order traversal(root) is traversing the left sub-tree of the node then the node ...
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;
};

Glass.Mapper.Sc allows you to move your data from Sitecore and into your code seamlessly using strongly typed objects.
The framework allows you to map data on to c# classes and interfaces without any additional mark-up. As the data is mapped to your target objects it is converted to the target type...
Visual Basic for Applications (VBA) is the macro language behind all Microsoft Office products and is essentially identical across all Office products. What differs from product to product is the Object model. Excel has workbooks, worksheets and cells. Access has tables and attributes. Outlook h...
