jok3333 [9.3K]

Answer:

The following are code in the Java Programming Language.

//define boolean type function

boolean isReverse(int ar[], int b[])

{

//declare integer type variable

int x;

//set the for loop

for (x=0; x < ar.length && ar[x] == b[ar.length-1-x]; x++);

return x == ar.length;

}

Explanation:

The following are the description of the code.

In the above code that is written in the Java Programming Language, we define the boolean data type function that is 'is Reverse()' and pass two array integer data type arguments that is 'ar', 'b' in the then, declare integer data type variable that is 'x'. Set the for loop that the boolean type value is true or false.

Zanzabum

Answer:

TRUE

Explanation:

A rootkit is a collection of computer software, typically malicious, that is designed to grant an unauthorized user access to a computer or certain programs. Once a rootkit is installed, it is easy to mask its presence, so an attacker can maintain privileged access while remaining undetected.

Rootkit detection is difficult because a rootkit maybe able to subvert the software that is intended to find it.

Rootkits work by using a process called modification (the changing of user account permissions and security).

Rootkits are not malware themselves, but rather a process used to deploy malware on a target.

Therefore, it is TRUE that a rootkit is software and file folders that are hidden from view and permit viruses, spyware, and malware to be installed on a PC without the knowledge or consent of a user.

To reduce the number of used digital outputs of the microcontroller, the display board is connected to the main board through th

Luda [366]

Answer:

The program in Python is as follows:

BCD = ["0001","0010","0011","0100","0101","0110","0111"]

num = input("Decimal: ")

BCDValue = ""

valid = True

for i in range(len(num)):

if num[i].isdigit():

if(int(num[i])>= 0 and int(num[i])<8):

BCDValue += BCD[i]+" "

else:

valid = False

break;

else:

valid = False

break;

if(valid):

print(BCDValue)

else:

print("Invalid")

Explanation:

This initializes the BCD corresponding value of the decimal number to a list

BCD = ["0001","0010","0011","0100","0101","0110","0111"]

This gets input for a decimal number

num = input("Decimal: ")

This initializes the required output (i.e. BCD value) to an empty string

BCDValue = ""

This initializes valid input to True (Boolean)

valid = True

This iterates through the input string

for i in range(len(num)):

This checks if each character of the string is a number

if num[i].isdigit():

If yes, it checks if the number ranges from 0 to 7 (inclusive)

if(int(num[i])>= 0 and int(num[i])<8):

If yes, the corresponding BCD value is calculated

BCDValue += BCD[i]+" "

else:

If otherwise, then the input string is invalid and the loop is exited

valid = False

break;

If otherwise, then the input string is invalid and the loop is exited

else:

valid = False

break;

If valid is True, then the BCD value is printed

if(valid):

print(BCDValue)

If otherwise, it prints Invalid

else:

print("Invalid")
