A common problem in parsing computer languages and compiler implementations is determining if an input string is balanced. That is, a string can be considered balanced if for every opening element ( (, [, <, etc) there is a corresponding closing element ( ), ], >, etc).
Today, we’re interested in writing a method that will determine if a String is balanced. Write a method, isBalanced(String s) that returns true if every opening element is matched by a closing element of exactly the same type. Extra opening elements, or extra closing elements, result in an unbalanced string. For this problem, we are only interested in three sets of characters -- {, (, and [ (and their closing equivalents, }, ), and ]). Other characters, such as <, can be skipped. Extra characters (letters, numbers, other symbols) should all be skipped. Additionally, the ordering of each closing element must match the ordering of each opening element. This is illustrated by examples below.
The following examples illustrate the expected behaviour:
is Balanced ("{{mustache templates use double curly braces}}") should return true
is Balanced("{{but here we have our template wrong!}") should return false
is Balanced("{ ( ( some text ) ) }") should return true
is Balanced("{ ( ( some text ) } )") should return false (note that the ordering of the last two elements is wrong)
Write an implementation that uses one or more Stacks to solve this problem. As a client of the Stack class, you are not concerned with how it works directly, just that it does work.
Answer:
Explanation:
import java.util.*;
public class BalancedBrackets {
// function to check if brackets are balanced
static boolean isBalanced(String expr)
{
Stack<Character> stack = new Stack<Character>();
for (int i = 0; i < expr.length(); i++)
{
char x = expr.charAt(i);
if (x == '(' || x == '[' || x == '{')
{
// Push the element in the stack
stack.push(x);
continue;
}
if (stack.isEmpty())
return false;
char check;
switch (x) {
case ')':
check = stack.pop();
if (check == '{' || check == '[')
return false;
break;
case '}':
check = stack.pop();
if (check == '(' || check == '[')
return false;
break;
case ']':
check = stack.pop();
if (check == '(' || check == '{')
return false;
break;
}
}
// Check Empty Stack
return (stack.isEmpty());
}
public static void main(String[] args)
{
Scanner scan = new Scanner(System.in);
System.out.println("\nEnter the expression to check is balanced or not !");
String expr = scan.nextLine();
boolean output;
output = isBalanced(expr);
System.out.println(output);
if (output)
System.out.println("Balanced ");
else
System.out.println("Not Balanced ");
scan.close();

Preserving confidentiality, integrity, and availability is a restatement of the concern over interruption, interception, modification, and fabrication.
i. Briefly explain the 4 attacks: interruption, interception, modification, and fabrication.
ii. How do the first three security concepts relate to these four attacks
Answer and Explanation:
I and II answered
Interruption: interruption occurs when network is tampered with or communication between systems in a network is obstructed for illegitimate purposes.
Interception: interception occurs when data sent between systems is intercepted such that the message sent to another system is seen by an unauthorized user before it reaches destination. Interception violates confidentiality of a message.
Modification: modification occurs when data sent from a system to another system on the network is altered by an authorized user before it reaches it's destination. Modification attacks violate integrity, confidentiality and authenticity of a message.
Fabrication: fabrication occurs when an unauthorized user poses as a valid user and sends a fake message to a system in the network. Fabrication violates confidentiality, integrity and authenticity.
Write a method swapArrayEnds() that swaps the first and last elements of its array parameter. Ex: sortArray
I understand you want a function that swaps the first and last element of an array so that the first element takes the last one's value and vice versa.
Answer and Explanation:
Using Javascript programming language:
function swapArrayEnds(sortArray){
var newArray= sortArray.values();
var firstElement=newArray[0];
newArray[0]=newArray[newArray.length-1];
newArray[newArray.length-1]=firstElement;
return newArray;
}
var exampleArray=[2, 5, 6, 8];
swapArrayEnds(exampleArray);
In the function above we defined the swapArray function by passing an array parameter that is sorted by swapping its first and last element. We first get the elements of the arrayvusing the array values method. We then store the value of the first element in the variable firstElement so that we are able to retain the value and then switch the values of the first element before using the firstElement to switch value of the last element. We then return newArray and call the function.

Answer:
You typically create a database during Oracle Database software installation. However, you can also create a database after installation.
Reasons to create a database after installation are as follows:
You used Oracle Universal Installer (OUI) to install software only, and did not create a database. You want to create another database (and database instance) on the same host computer as an existing Oracle database. In this case, this chapter assumes that the new database uses the same Oracle home as the existing database. You can also create the database in a new Oracle home by running OUI again. You want to make a copy of (clone) a database.

Would you prefer to use an integrated router, switch, and firewall configuration for a home network, or would you prefer to operate them as separate systems
Answer:
I would prefer to use an integrated router, switch, and firewall configuration for a home network instead of operating my home devices as separate systems.
Explanation:
Operating your home devices as separate systems does not offer the required good service in information sharing. To share the internet connection among the home devices, thereby making it cheaper for family members to access the internet with one Internet Service Provider (ISP) account rather than multiple accounts, a home network is required. A home network will always require a network firewall to protect the internal/private LAN from outside attack and to prevent important data from leaking out to the outside world.
