In a linked chain implementation of a queue, the performance of the enqueue operation

alexdok [17]

Answer:

A.O(1)

Explanation:

In the implementation of queue by using linked chain the performance of the enqueue operation is O(1).We have to maintain two pointers one head and the other tailand for enqueue operation we have to insert element to the next of the tail and then make that element tail.Which takes O(1) time.

In Java.Use a single for loop to output odd numbers, even numbers, and an arithmetic function of an odd and even number. Use the

rosijanka [135]

Answer:

This program is written using java programming language

Difficult lines are explained using comments (See Attachment for Source file)

Program starts here

import java.util.*;

import java.lang.Math;

public class oddeven{

public static void main(String [] args)

{

double even,odd;//Declare variables even and odd as double

//The next iteration prints odd numbers

for(int i = 1;i<=173;i+=2)

{

odd = i;

System.out.format("%.4f",odd);//Round to 4 decimal places and print

System.out.print("\t");

}

System.out.print('\n');//Start printing on a new line

//The next iteration prints even numbers

for(int i = 0;i<=173;i+=2)

{

even=i;

System.out.format("%.4f",even);//Round to 4 decimal places and print

System.out.print("\t");

}

System.out.print('\n');//Start printing on a new line

double ssqrt;//Declare ssqrt to calculate the square root of sum of even and odd numbers

for(int i = 0;i<=173;i+=2)

{

ssqrt = Math.sqrt(2*i+1);//Calculate square root here

System.out.format("%.4f",ssqrt); //Round to 4 decimal places and print

System.out.print("\t");

}

Explanation:

Libraries are imported into the program

import java.util.*;

import java.lang.Math;

The following line declares variables even and odd as double

double even,odd;

The following iteration is used to print odd numbers with in the range of 0 to 173

for(int i = 1;i<=173;i+=2) {

odd = i;

System.out.format("%.4f",odd); This particular line rounds up each odd numbers to 4 decimal places before printing them

System.out.print("\t"); This line prints a tab

}

The following code is used to start printing on a new line

System.out.print('\n');

The following iteration is used to print even numbers with in the range of 0 to 173

for(int i = 0;i<=173;i+=2)

{

even=i;

System.out.format("%.4f",even); This particular line rounds up each even numbers to 4 decimal places before printing them

System.out.print("\t"); This line prints a tab

}

The following code is used to start printing on a new line

System.out.print('\n');

The next statement declares ssqrt as double to calculate the square root of the sum of even and odd numbers

double ssqrt;

for(int i = 0;i<=173;i+=2)

{

ssqrt = Math.sqrt(2*i+1);This line calculates the square root of sum of even and odd numbers

System.out.format("%.4f",ssqrt); This particular line rounds up each even numbers to 4 decimal places before printing them

System.out.print("\t"); This line prints a tab

{

ArrayList<Integer> listNew=new ArrayList<Integer>();

{

listNew.add(list.get(i));

}

list.removeAll(listNew); //removing all elements from list.

}

public static void main(String[] args)

{

list.add(7);

Scanner sc=new Scanner(System.in);

System.out.println("Enter min : ");

int min=sc.nextInt();

System.out.println("Enter Max : ");

int max= sc.nextInt();

filterRange(list, min, max);

//Displaying new List

for(int i=0;i<list.size();i++)

{

System.out.print(list.get(i)+" ");
