Java !!!
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.

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);

Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a comma, including the last one.Ex: If the input is:5 2 4 6 8 10the output is:10,8,6,4,2,To achieve the above, first read the integers into a vector. Then output the vector in reverse.

Answers

Answer:

The program in C++ is as follows:

#include <iostream>

#include <vector>

using namespace std;

int main(){

   vector<int> intVect;

   int n;

   cin>>n;

int intInp;

for (int i = 0; i < n; i++) {

 cin >> intInp;

 intVect.push_back(intInp); }

for (int i = n-1; i >=0; i--) {  cout << intVect[i] << " "; }

 return 0;

}

Explanation:

This declares the vector

   vector<int> intVect;

This declares n as integer; which represents the number of inputs

   int n;

This gets input for n

   cin>>n;

This declares intInp as integer; it is used to get input to the vector

int intInp;

This iterates from 0 to n-1

for (int i = 0; i < n; i++) {

This gets each input

 cin >> intInp;

This passes the input to the vector

 intVect.push_back(intInp); }

This iterates from n - 1 to 0; i.e. in reverse and printe the vector elements in reverse

for (int i = n-1; i >=0; i--) {  cout << intVect[i] << " "; }

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");

}

The program is an illustration of conditional statements

Conditional statements are used to make decisions

The program in C++ where comments are used to explain each line is as follows

// This prompts the user for input (i.e. the amount)

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;

amount = amount%25;

dime = amount/10;

amount = amount%10;

nickel = amount/5;

penny = amount%5;

// The next lines print the coins

Write a recursive function that returns 1 if an array of size n is in sorted order and 0 otherwise. Note: If array a stores 3, 6, 7, 7, 12, then isSorted(a, 5) should return 1 . If array b stores 3, 4, 9, 8, then isSorted(b, 4) should return 0.

Answers

Answer:

The function in C++ is as follows:

int isSorted(int ar[], int n){

if ([tex]n == 1[/tex] || [tex]n == 0[/tex]){

 return 1;}

if ([tex]ar[n - 1][/tex] < [tex]ar[n - 2][/tex]){

 return 0;}

return isSorted(ar, n - 1);}

Explanation:

This defines the function

int isSorted(int ar[], int n){

This represents the base case; n = 1 or 0 will return 1 (i.e. the array is sorted)

if ([tex]n == 1[/tex] || [tex]n == 0[/tex]){

 return 1;}

This checks if the current element is less than the previous array element; If yes, the array is not sorted

if ([tex]ar[n - 1][/tex] < [tex]ar[n - 2][/tex]){

 return 0;}

This calls the function, recursively

return isSorted(ar, n - 1);

}
