9.18 LAB: Exact change - methods Write a program with total change amount as an integer input that outputs the change using the fewest coins, one coin type per line. The coin types are dollars, quarters, dimes, nickels, and pennies. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies. Ex: If the input is:
Answers
Answer:
Explanation:
The following code is written in Java. It asks the user to enter the amount of change needed. This is done as a double since we are dealing with coins and not full dollar values alone. It then makes the necessary calculations to calculate the number of each coin needed and outputs it back to the user. A test case has been provided in the picture below with a sample output.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
int dollars = 1;
double quarters = 0.25;
double dimes = 0.10;
double nickels = 0.05;
double pennies = 0.01;
Scanner in = new Scanner(System.in);
System.out.println("Enter Change Value: ");
double change = in.nextDouble();
int numDollars, numQuarters, numDimes, numNickels, numPennies;
double newChange;
numDollars = (int) (change / dollars);
newChange = change % dollars;
numQuarters = (int) (newChange / quarters);
newChange = newChange % quarters;
numDimes = (int) (newChange / dimes);
newChange = newChange % dimes;
numNickels = (int) (newChange / nickels);
newChange = newChange % nickels + 0.001;
numPennies = (int) (newChange / pennies);
newChange = newChange % pennies;
System.out.println("Minimum Num of Coins needed: ");
if (numDollars != 1) {
System.out.println(numDollars + " Dollars");
} else {
System.out.println(numDollars + " Dollar");
}
if (numQuarters != 1) {
System.out.println(numQuarters + " Quarters");
} else {
System.out.println(numQuarters + " Quarter");
}
if (numDimes != 1) {
System.out.println(numDimes + " Dimes");
} else {
System.out.println(numDimes + " Dime");
}
if (numNickels != 1) {
System.out.println(numNickels + " Nickels");
} else {
System.out.println(numNickels + " Nickel");
}
if (numPennies != 1) {
System.out.println(numPennies + " Pennies");
} else {
System.out.println(numPennies + " Penny");
}
}
}
The program is an illustration of conditional statements
Conditional statements are used to make decisions

cout<<"Amount: ";
//This gets the amount from the user
cin>>amount;
// This checks if the amount is 0 or less
if(amount<=0) {
//This prints "No Change"
cout<<"No Change";
}
//If the amount is greater than 0
else {
// These convert the amount to various coins
dollar = amount/100;
amount = amount%100;
quarter = amount/25;

SQLite is a database that comes with Android. Which statements is/are correct?
The content of an SQLite database is stored in XML formatted files because XML is the only file format supported by Android OS.
A SQLite database is just another name for a Content Provider. There is no difference as the SQLite implementation implements the Content Provider interface.
If an app creates an SQLite database and stores data in it, then all of the data in that particular database will be stored in one, single file.
A database query to an SQLite database usually returns a set of answers
To access individual entries, SQLite provides a so-called Cursor to enumerate all entries in the set.
This is yet another example of the Iterator pattern.
Answers
Answer:
1. Wrong as per my knowledge, SQLite may be an electronic database software that stores data in relations(tables).
2. Wrong. Content provider interface controls the flow of knowledge from your android application to an external data storage location. Data storage is often in any database or maybe it'll be possible to store the info in an SQLite database also.
3.Right. SQLite uses one file to store data. It also creates a rollback file to backup the stored data/logs the transactions.
4. Wrong. The queries are almost like a traditional electronic database system, the queries are going to be answered as per the conditions given and should return a group of answers or one answer depending upon the info and sort of query used.
5. Right. A cursor helps to point to one entry within the database table. this may be very helpful in manipulating the present row of the query easily.

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.

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.
Answers
Answer:
Explanation:
import java.util.*;
public class BalancedBrackets {
// function to check if brackets are balanced

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 == '[')

Write a method swapArrayEnds() that swaps the first and last elements of its array parameter. Ex: sortArray
Answers
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.
Calculate how much disk space (in sectors, tracks, and surfaces) will be required to
store 300,000 120-byte logical records if the disk is fixed sector with 512 bytes/
sector, with 96 sectors/track, 110 tracks per surface, and 8 usable surfaces. Ignore
any file header record(s) and track indexes, and assume that records cannot span
two sectors.
It will be great if you could explain the answer to me. :)

The amount of disk space in sectors that would be required to store 300,000 records is equal to 75,000 sectors.
Given the following data:
Number of records = 300,000.Size of each logical record = 120 byte.Number of bytes (sector) = 512.Number of sectors per track = 96.Number of tracks per surface = 110.How to calculate the required disk space?First of all, we would determine the number of logical records that can be held by each sector as follows:
Number of logical records per sector = 512/120
Number of logical records per sector = 4.3 ≈ 4.0.
Now, we can calculate the required disk space to store 300,000 records:
Disk space = 300,000/4
Disk space = 75,000 sectors.
For the tracks, we have:
Disk space in tracks = 75,000/96
Disk space in tracks = 781.25 ≈ 782.
Disk space in tracks = 782 tracks.
For the surfaces, we have:
Disk space in surfaces = 782/110
Disk space in surfaces = 7.10 ≈ 8.
Disk space in surfaces = 8 surfaces.
