Answer:

See explaination

Explanation:

public class PalindromeChange {

public static void main(String[] args) {

System.out.println("mom to non palindrom word is: "+changTONonPalindrom("mom"));

System.out.println("mom to non palindrom word is: "+changTONonPalindrom("aaabbaaa"));

}

private static String changTONonPalindrom(String str)

{

int mid=str.length()/2;

boolean found=false;

char character=' ';

int i;

for(i=mid-1;i>=0;i--)

{

character = str.charAt(i);

if(character!='a')

{

found=true;

break;

}

if(!found)

{

for(i=mid+1;i<str.length();i++)

{

character = str.charAt(i);

if(character!='a')

{

found=true;

break;

}

// This gives the character 'a'

int ascii = (int) character;

ascii-=1;

str = str.substring(0, i) + (char)ascii+ str.substring(i + 1);

return str;

}

If the object instance is created in a user program, then the object instance can access both the public and private members of

rewona [7]

Answer:

False

Explanation:

The private member of a class is not accessible by using the Dot notation ,however the private member are those which are not accessible inside the class they are accessible outside the class .The public member are accessible inside the class so they are accessible by using the dot operator .

Following are the example is given below in C++ Language

#include<iostream> // header file

using namespace std;

class Rectangle

{

private:

double r; // private member

public:

double area()

{ return 3.14*r*r;

}

};

int main()

{

Rectangle r1;// creating the object

r1.r = 3.5;

double t= r1.area(); // calling

cout<<" Area is:"<<t;

return 0;

}

Output:

compile time error is generated

The correct program to access the private member of class is given below

#include<iostream> // header file

using namespace std;

class Rectangle

{

private:

double r; // private member

public:

double area()

{

r1=r;

double t2=3.14*r2*r2;

return(t2); // return the value

}

};

int main()

{

Rectangle r1;// creating the object

r1.r = 1.5;

double t= r1.area(); // calling

cout<<" Area is:"<<t;

return 0;

}

Therefore the given statement is False

Suppose that the data mining task is to cluster points (with (x, y) representing location) into three clusters, where the points

solong [7]

Answer:

Explanation:

K- is the working procedure:

It takes n no. of predefined cluster as input and data points.

It also randomly initiate n centers of the clusters.

In this case the initial centers are given.

Steps you can follow

Step 1. Find distance of each data points from each centers.

Step 2. Assign each data point to the cluster with whose center is nearest to this data point.

Step 3. After assigning all data points calculate center of the cluster by taking mean of data points in cluster.

repeat above steps until the center in previous iteration and next iteration become same.

A1(4,8), A2(2, 4), A3(1, 7), B1(5, 4), B2(5,7), B3(6, 6), C1(3, 7), C2(7,8)

Centers are X1=A1, X2=B1, X3=C1

A1 will be assigned to cluster1, B1 will be assigned to cluster2 ,C1 will be assigned to cluster3.

Go through the attachment for the solution.

Which statement below correctly differentiates between frames and bits? Frames have more information in them than bits. Frames a

9966 [12]

Frames have more information in them than bits.

Frames are made up of bits but not vice versa.

A bit (BInary digiT) is the basic unit of digital. It can be 0 (logical false, off) or 1 (not logical false - true, on). Four bits are in a nybble, which can have a value of 0 - 15, eight bits are in a byte which can have a value of 0 - 255. Words vary in size, they consist of multiple bytes and are generally correlated with the system's data bus/processor data width (a 64 bit system has an 8 byte word).
