Answer:

import java.util.Comparator;

import java.util.PriorityQueue;

 

public class PriorityQueueTest {

 

static class PQsort implements Comparator<Integer> {

 

 public int compare(Integer one, Integer two) {

 return two - one;

 }

}

 

public static void main(String[] args) {

 int[] ia = { 1, 10, 5, 3, 4, 7, 6, 9, 8 };

 PriorityQueue<Integer> pq1 = new PriorityQueue<Integer>();

 

 // use offer() method to add elements to the PriorityQueue pq1

 for (int x : ia) {

 pq1.offer(x);

 }

 

 System.out.println("pq1: " + pq1);

 

 PQsort pqs = new PQsort();

 PriorityQueue<Integer> pq2 = new PriorityQueue<Integer>(10, pqs);

 // In this particular case, we can simply use Collections.reverseOrder()

 // instead of self-defined comparator

 for (int x : ia) {

 pq2.offer(x);

 }

 

 System.out.println("pq2: " + pq2);

 

 // print size

 System.out.println("size: " + pq2.size());

 // return highest priority element in the queue without removing it

 System.out.println("peek: " + pq2.peek());

 // print size

 System.out.println("size: " + pq2.size());

 // return highest priority element and removes it from the queue

 System.out.println("poll: " + pq2.poll());

 // print size

 System.out.println("size: " + pq2.size());

 

 System.out.print("pq2: " + pq2);

 

}

}

SSSSS [86.1K]

Answer:

Following are the code to this question:

#include<stdio.h>//defining header file

int AND(int x,int y) //defining a method AND that hold two variable in its parameter

{

if(x==1 && y==1)//defining if block to check x and y value is equal to 1

{

return 1;//return value 1

}

else //defining else block

{

   return 0;//return value 0

}

}

int OR(int x,int y)//defining method OR that hold two variable in its parameter

{

if(x==0&&y==0)//defining if block to check x and y value is equal to 1

{

return 0;//return value 0

}

else //defining else block

{

   return 1;//return value 1

}

}

int main()//defining main method

{

int a,b,c;//defining integer variable  

int k=1;//defining integer variable k that holds a value 1

while(k<=8)//defining while loop for 8 time input

{

printf("Please insert 3 numbers in (0 0r 1):\n ");//print message

scanf("%d%d%d", &a, &b, &c);//input value

k++;//increment the value of k by 1

printf("value: %d\n",AND(OR(a,b),c));

}

return 0;

}

Output:

please find the attachment.

Explanation:

In the above-given C language code two methods "AND and OR" is declared, holds two integer variable "x and y" in its parameters, inside the method a conditional it used that can be defined as follows:

  • In the AND method, inside a conditional statement, if block check x and y both value is same that is 1 it will return 1 or it will goto else block in this it will return value 0.      
  • In the OR method, inside a conditional statement, if block check x and y both value is the same, that is 0 it will return 0 or it will goto else block in this it will return value 1.
  • In the main method, four integers "a,b,c, and k" is declared in which variable "a, b, c" is used in the loop for 8 times input values from the user and print method is used to call the method and prints its return values.

5.19 LAB: Exact change - functions
matrenka [14]

Answer:

def exact_change(user_total):

    if user_total <=0:

         print("No change")

    else:

         num_dollars = int(user_total/100)

         user_total = user_total % 100

         num_quarters= int(user_total/25)

         user_total = user_total % 25

         num_dimes= int(user_total/10)

         user_total = user_total % 10

         num_nickels= int(user_total/5)

         num_pennies= user_total % 5

         if num_dollars >= 1:

              if num_dollars == 1:

                   print(str(num_dollars)+" num_dollars")

              else:

                   print(str(num_dollars)+" amountdollars")

         if num_quarters>= 1:

              if num_quarters== 1:

                   print(str(num_quarters)+" quarter")

              else:

                   print(str(num_quarters)+" quarters")

         if num_dimes>= 1:

              if num_dimes== 1:

                   print(str(num_dimes)+" dime")

              else:

                   print(str(num_dimes)+" dimes")

         if num_nickels>= 1:

              if num_nickels== 1:

                   print(str(num_nickels)+" nickel")

              else:

                   print(str(num_nickels)+" nickels")

         if num_pennies>= 1:

              if num_pennies== 1:

                   print(str(num_pennies)+" penny")

              else:

                   print(str(num_pennies)+" pennies")

           

user_total = int(input("Enter user_total Here:  "))

Write the definition of a function named quadratic that receives three double parameters a, b, c. If the value of a is 0 then th
VMariaS [17]

Answer:

#include <iostream>

#include <cmath>

using namespace std;

//initialize function quadratic

void quadratic(double, double, double);

int main() {

   //declare double variables a, b and c

   double a,b,c;

   //take input from user

   cin>>a>>b>>c;

   //call function quadratic

   quadratic(a,b,c);

return 0;

}

void quadratic(double a, double b, double  c){

   double root,n;

   //check if variable a is equal to zero

   if(a==0){

       cout<<"no solution for a=0"<<endl;

       return;

   }

   //check if b squared - 4ac is less than zero

   else

   if(((b*b)-(4*a*c))<0){

       cout<<"no real solutions"<<endl;

       return;

   }

   //print the largest root if the above conditions are not satisfied

   else{

       n=((b*b)-(4*a*c));

       root=(-b + sqrt(n)) / (2*a);

       cout<<"Largest root is:"<<root<<endl;

   }

   return ;

}

Explanation:

Read three double variables a, b and c from the user and pass it to the function quadratic. Check if the value of variable a is equal to zero. If true, print "no solution for a=0". If this condition is false, check if b squared - 4ac is less than zero. If true, print "no real solutions". If this condition is also false, calculate the largest solution using the following formula:

largest root = (-b + square root of (b squared - 4ac)) / (2*a)

Input 1:

2 5 3

Output 2:

Largest root is:-1

Input 2:

5 6 1

Output 2:

Largest root is:-0.2

Feliz [49]

Answer:

check the explanation

Explanation:

Variables when it comes to programming are used to store data to be documented and manipulated in a computer program. They can also be used for labeling stored data with a descriptive name and any other needed details, so that the programs can be comprehended more understandably by the reader and ourselves.

to solve the question, we will write this set of codes;

numberOfIncompletes = 0;

for(k = 0; k < incompletes.length; k++)

{

       if(incompletes[k] == studentID)

           numberOfIncompletes++;

}
