3. Let A = {1, 5, 7, 11}. Show that (A, *) is a group, where * is a binary operator defined as x * y = (x ⋅ y) mod 24. Determine the identity and the inverse of each element. 4. Consider the group A in Exercise 3, a. Prove or disprove that A has a subgroup of order 2. b. Prove or disprove that A has a subgroup of order 3.

Answer:

1.Communication Management

2.Information Management

Explanation:

NIMS has introduced COMMUNICATION management system that determines if the decision makers has the ways to communicate decisions. It has standards that defines the ways that can be used by the personnel to communicate the decisions in a better and efficient manner.

NIMS has also a system which is primarily introduced to check the the personnel has the information to make and communicate decisions called Information management. Again, it also has the templates that defines that how information should be spread considering the confidentiality of the information.

Answer:

The given statement is "False".

Explanation:

Mainframes computer are also known big iron computer basically Mainframe computer is used by the big organization when the organization needs to work in the high-level project. The mainframe has big data processing. It is highly used in critical applications such as ERP(Enterprise resource planning).

A mainframe computer is not a flexible computer also they are not potable .microcomputers, are more flexible computers we can easily work on the microcomputers.

So the given statement is False.

Explanation:

I'm going to assume this is Java, because you said "method" meaning it will be some sort of object oriented language, and Java's really common. Here would be the full program, but you can just take the method out isolated if you need it.

package lastname;

public class LastName {

   public static void main(String[] args) {

       // Example usage:

       String name = LastName.lastName("Garrett Acord");

       System.out.println(name);

       // Output: Acord G.

   }

   public static String lastName(String fullName)

   {

       String[] splitName = fullName.split(" ");

       return String.format("%s %s.", splitName[1], splitName[0].substring(0,1) );

   }

}

Answer:

The program to this question can be given as:

Program:

#include <iostream>  //header file

using namespace std;  //using name space.

int CountCharacters(char userChar,string userString) //define function.

{    

int count = 0;  //define variable

for (int i=0;i<userString.length();i++) //loop

if (userString[i]==userChar)  //if block

count++;  //increment the value.

return count;  //return value.

}

int main()  //main method.

{

   string userString= "Clanguage";  //define variable and assign value.

   char userChar = 'a';   //define variable and assign value.

   cout << CountCharacters(userChar,userString);  //calling function and print value.  

   return 0;  

}

Output:

2

Explanation:

• In the above C++ programming language program we define a function that is "CountCharacters". Inside function parameters, we pass two parameters that are "userChar and userString". The userChar is a char variable that holds single character value and userString is a string variable that holds a string value.
• In the function, we define an integer variable that is "count". This variable counts the match value and returns its value.
• To counts values, we define a loop in a loop we use if statement that counts the value that how many time it occurs in a string value and return its value.
• In the main method, we define these variables ("userChar and userString") and assign values that are "a and Clanguage " and call the function and print function return value.
