1).Virus :- A type of malware that spreads through normal program.It could simply slow down your device down or cause you to lose all access to programs on your computer.

2).Spyware:- A type of malware that installs itself onto devices and steals personal information about the user like usernames and passwords.It tracks every key the user pressed called key logging.

3).Worm:- This type of malware can copy itself hundreds of times so can hard your device very quickly.

4). Trojan Horse :- This type of malware pretends it will be useful and it is a safe program when it will actually try and attack your device.

When reading data across the network (i.e. from a URL) in Python 3, what string method must be used to convert it to the interna

EastWind [94]

Answer:

decode( )

Explanation:

We can use the method decode( ) to decode the string using the codec registered for encoding.

There are two parameters

encoding: We can encode with this parameter.

errors: If used to manage the errors.

For example:

String = "this is string example....wow!!!";

String = Str.encode('base64','strict');

If we print these variables we have:

String = b'dGhpcyBpcyBzdHJpbmcgZXhhbXBsZS4uLi53b3chISE='

String = this is string example....wow!!!

When Judy logged on the network, she faced the message requesting that she changes her password. So, she changed her password. B

jeka94

Answer:

Because reusing the old passwords possess security threats.

Explanation:

A password can be defined as a string of characters or words or phrases that are used to authenticate the identity of the user. It is also known as passcode and should be kept confidential. A password is used to access constricted systems, applications, etc.

A password or passcode is usually composed of alphabets, numbers, symbols, characters, alphanumeric, or a combination of these.

<u>In the given case, Judy was not able to change her passcode to the previous one because reusing old passwords is prohibited in any sites or systems. A system denies the user to reuse the old passwords for various reasons but most importantly due to security reasons. Though it is said that old passwords can be used after 100 times but seldom someone changes a password that much. All systems care for the security of their users thus they deny reusing old passcodes.</u>

Write the method makeNames that creates and returns a String array of new names based on the method’s two parameter arrays, arra

Gwar [14]

Answer:

import java.util.Arrays;
public class Main {
public static void main(String[] args) {
String [] first = {"David", "Mike", "Katie", "Lucy"};
String [] middle = {"A", "B", "C", "D"};
String [] names = makeNames(first, middle);
System.out.println(Arrays.toString(names));
}
public static String [] makeNames(String [] array1, String [] array2){
if(array1.length == 0){
return array1;
}
if(array2.length == 0){
return array2;
}
String [] newNames = new String[array1.length];
for(int i=0; i < array1.length; i++){
newNames[i] = array1[i] + " " + array2[i];
}
return newNames;
}
}

Explanation:

The solution code is written in Java.

Firstly, create the makeNames method by following the method signature as required by the question (Line 12). Check if any one the input string array is with size 0, return the another string array (Line 14 - 20). Else, create a string array, newNames (Line 22). Use a for loop to repeatedly concatenate the string from array1 with a single space " " and followed with the string from array2 and set it as item of the newNames array (Line 24-26). Lastly, return the newNames array (Line 28).

In the main program create two string array, first and middle, and pass the two arrays to the makeNames methods as arguments (Line 5-6). The returned array is assigned to names array (Line 7). Display the names array to terminal (Line 9) and we shall get the sample output: [David A, Mike B, Katie C, Lucy D]

A contiguous subsequence of a list S is a subsequence made up of consecutive elements of S. For example, if S is 5,15,-30,10,-5,

Sindrei [870]

Answer:

We made use of the dynamic programming method to solve a linear-time algorithm which is given below in the explanation section.

Explanation:

Solution

(1) By making use of the dynamic programming, we can solve the problem in linear time.

Now,

We consider a linear number of sub-problems, each of which can be solved using previously solved sub-problems in constant time, this giving a running time of O(n)

Let G[t] represent the sum of a maximum sum contiguous sub-sequence ending exactly at index t

Thus, given that:

G[t+1] = max{G[t] + A[t+1] ,A[t+1] } (for all 1<=t<= n-1)

Then,

G[0] = A[0].

Using the above recurrence relation, we can compute the sum of the optimal sub sequence for array A, which would just be the maximum over G[i] for 0 <= i<= n-1.

However, we are required to output the starting and ending indices of an optimal sub-sequence, we would use another array V where V[i] would store the starting index for a maximum sum contiguous sub sequence ending at index i.

Now the algorithm would be:

Create arrays G and V each of size n.

G[0] = A[0];

V[0] = 0;

max = G[0];

max_start = 0, max_end = 0;

For i going from 1 to n-1:

// We know that G[i] = max { G[i-1] + A[i], A[i] .

If ( G[i-1] > 0)

G[i] = G[i-1] + A[i];

V[i] = V[i-1];

Else

G[i] = A[i];

V[i] = i;

If ( G[i] > max)

max_start = V[i];

max_end = i;

max = G[i];

EndFor.

Output max_start and max_end.

The above algorithm takes O(n) time .
