What is BAT?

 

The Basic Attention Token (BAT) was created by the co-founder of Mozilla and Firefox, Brendan Eich, to improve the security, fairness, and efficiency of digital advertising through blockchain technology. It is the native token of the Brave web browser built on top of Ethereum (ETH).

 

Note: Brendan Eich also created JavaScript 😮. So you can imagine now how important it is.

 

There are three different entities in the world of market:

Audience

Content Publishers

Advertisers

Now a days everyone is using ad blocker in the browser so it is not beneficial for the advertisers to pay for ads to Google or some other company when they know that ads will be blocked by the user.

So now what to do?

Here Brave comes.

Brave gives audience some rewards for watching the ads and in this process no data stealing is done.

Data is not sent to the advertisers or the one who publish ads.

So now advertisers are aware that, yes someone is there who is watching our ads and BAT helps for all three entities equally.

 

 

Bubble Sort

 Bubble Sort is a sorting algorithm and this algorithm is used to sort (arranging the elements in ascending or descending order) arrays/list.

Application

Understand the working of Bubble sort

• Bubble sort is mainly used in educational purposes for helping students understand the foundations of sorting.
• This is used to identify whether the list is already sorted. When the list is already sorted (which is the best-case scenario), the complexity of bubble sort is only O(n).
• In real life, bubble sort can be visualized when people in a queue wanting to be standing in a height wise sorted manner swap their positions among themselves until everyone is standing based on increasing order of heights.

Algorithm:

ALGORITHM bubble_sort(a[], size){

    for(i=size-1;i>0;i--){

        for(j=0;j<size-1;j++){

            //when adjacent nodes have greater value

            if(a[j] > a[j+1]{

                swap(a[j],a[j+1]);

            }

        }//end of child for loop

    }//end of parent for loop

}//end of bubble_sort function

Pseudo Code:

#include<iostream>

using namespace std;

void bubble_sort(int a[],int size){

    bool is_swapped = false;

       

    for(int i=size-1;i>0;i--){

        for(int j=0;j<i;j++){

            //check whether the fist element is bigger or not

            if(a[j] > a[j+1]){

                swap(a[j],a[j+1]);

                is_swapped = true;

            }

        }

        if(! is_swapped){

            break;

        }

    }

}

void print_array(int a[],int size){

    for(int i=0;i<size;i++){

        cout<<a[i]<<"\t";

    }

    cout<<endl;

}

int main(){

    int size = 10;

    int a[size] = {3,20,22,23,29,34,44,83,90,99};

    /**

     * sorted array of {34,23,44,90,29,20,3,99,83,22};

     * a = {3,20,22,23,29,34,44,83,90,99};

     *index 0  1  2  3  4  5  6  7  8  9

     */

    cout<<"Before sorting array: "<<endl;

    print_array(a,size);

    cout<<"After sorting array: "<<endl;

    bubble_sort(a,size);

    print_array(a,size);

    return 0;

}

Complexity:

Best Case          : O(n)

Worse Case       : O(n²)

Average Case    : O(n²)

Space                : O(n)

Auxiliary Space : 1 (no auxiliary space)

Inter Applet Communication

What is Inter Applet Communication ?

Inter Applet Communication means the communication of applets to each other in the same browser running simultaneously.
Lets understand it by an example:
suppose if there are 2 applets running in the browser that are applet1 and applet2.
Now suppose we want that when we click on the applet1's button then a message should be displayed on applet2
by using Inter Applet Communication we can do that thing and all those things that are related with the applet's communication.

Now the question is how can we do that?

so java.applet.AppletContext class provides the facility of communication between applets.
we provide the name of applets in the html file and by using this particular name with getApplet() method we can access the particular applet.

Syntax of getApplet() method:

public Applet getApplet(String appletName);

Program

first I am creating the html file named iac.html
<html>
<head>
<title>inter applet communication</title>
</head>
<body>
<applet code="Applet1.class" width="1000" height="500" name="applet1">
</applet>
<hr/>
<applet code="Applet2.class" width="1000" height="500" name="applet2">
</applet>
</body>
</html>

Applets

What is an Applet in java?

• Applet is an special java program that runs on the client's machine's browser.
• Applets are used to generate dynamic contents on the web page.

Today Applets are replaced by the java's Servlet but remember one thing that Servlet are not on client side but they are server side whereas Applets are client side.

what is meant by server side and client side?

What are the advantages and disadvantages of Applets?

Advantage of Applet

There are many advantages of applet. They are as follows:

• It works at client side so less response time.
• Secured
• It can be executed by browsers running under many platforms, including Linux, Windows, Mac Os etc.

Drawback of Applet

• Plugin is required at client browser to execute applet.

What is Aptitude?

What is Aptitude?
This is the question which you should ask to yourself someday at a moment of time(often it is when you are preparing for some exams like government jobs or for interviews of companies)
don't worry I am here and you will definitely know the answer of this question in this article so stay tuned.

Aptitude: It is none other than the ability to do something and what does something mean? By something I means in a certain level you need some abilities.
lets take an example: If you are a student than aptitude generally means logical reasoning(how you solve problems by using your mental powers), but if you are a housewife than the aptitude doesn't means logical reasoning or mathematical power, it means here cooking skills and most important is how a house manages the house.

Now clear one thing that you are specific in different-different regions and also you need different-different abilities to be master in your area or region.

Now why does edu which is a Computer Science Portal describing about Aptitude?
so dear understand one thing Aptitude is very important and keep one thing in mind that if you are in the first year or you are in preparation of companies interview then it is the very useful skill you must have in your skill toolkit.

Now if you are preparing for the companies interview than logical reasoning is that part you must learn, and in further upcoming articles we will deep go into it and will understand how to crack that.
