Complete the "Reducing pops and clicks" step-by-step found in Lesson 5 from the textbook “Adobe Audition CC Classroom in a Book.” After performing all the steps (1-9), save the file with the file name MajorPopsFix.wav and submit it.

Nice shirt! In Java, write a program that uses a function that takes in the user's name and prints out compliments directed to them. The program should provide a sentinel value by asking if they've had enough compliments and will continue until they type "yes". Include 3 different compliments pulled at random and BE SURE TO USE A FUNCTION/METHOD to take in the user's name.

Sample output:

Enter your name: John Smith

John Smith, you have a great smile!

Would you like another compliment? [yes/no] yes

John Smith, you are tall and handsome!

Would you like another compliment? [yes/no] yes

John Smith, you are a quick learner!

Would you like another compliment? [yes/no] no

Have a nice day!

Instructions

Submission Guidelines

This assignment may be submitted for full credit until Friday, October 4^th at 11:59pm. Late submissions will be accepted for one week past the regular submission deadline but will receive a 20pt penalty. Submit your work as a single HTML file. It is strongly recommended to submit your assignment early, in case problems arise with the submission process.

Assignment

For this assignment, you will write a timer application in HTML and JavaScript.

Your HTML document should contain the following elements/features:

1. HTML tags:
   1. An <input> tag labeled "Timer Duration" with the initial value 0
   2. A <button> tag labeled "Start"
2. Script: When the user presses the button (1b), a function will begin that does the following:
   1. Reads the value from the input field (1a)
   2. Removes the <input> and <button> tags (1a & 1b)
   3. Creates a new <p> tag, initialized to show the input value
   4. Starts a timer that ticks down to zero. For every second that elapses, the paragraph tag (2c) will show the updated timer value (i.e., one less)
   5. When the timer reaches zero, the countdown will stop and the paragraph tag (2c) will be removed and be replaced by a <button> tag labeled "New Timer"
   6. When the <button> tag (2e) is pressed, it will be removed and the <input> and <button> tags (1a, 1b) will be recreated with their original formats

Evaluation

Your assignment will be graded according to whether all the required elements are present and in the correct formats and all required functionalities are operable.

Javascript:

Create a loop that counts from 1 to 20. 
// If the current number is even, add it to this empty array:
var myArray = [];
// If the current number is odd, log an odd number warning to 
// the console.
// However, if the number equals 19, set a debug breakpoint.
// After the loop completes, print the array to the console.

var myArray = [];
for (var i = 1; i <= 20; i++) {
    if (i % 2 === 1) {
        console.warn("odd number");
    } else {
        myArray.push(i);
    }
    if (i === 19) {
        console.debug();
    }
}
console.log(myArray);

Vertex        Edge   Vertex
SFO        2702   BOS
SFO        1846   ORD
ORD         867   BOS
ORD         742   JFK
JFK         189   BOS
SFO        1464   DFW
DFW         802   ORD

LAX        2342   MIA

a) Find the shortest distance between
ORD and LAX.

b) Find the shortest distance between
JFK and SFO.

c) Find the minimum spanning tree.

For the problem below, please estimate the worst-case Running Time for a random array of size n, and prove that it is indeed ( ). Please show all your work. Just stating something like "since 2 Binary Search runs in ( ) time, our algorithm has the same runtime estimate" is not enough. A rigorous explanation is expected.

import java.util.*;
public class Main
{
static int binarySearch(int arr[], int l, int r, int x)
{
if (r >= l) {
int mid = l + (r - l) / 2;
  
// If the element is present at the middle itself
if (arr[mid] == x)
return mid;
  
// If element is smaller than mid, then it can only
// be present in left subarray
if (arr[mid] > x)
{ int rr= binarySearch(arr, l, mid - 1, x);
if(rr==-1)//modified
{
return binarySearch(arr, mid + 1, r, x);
}
return rr;
}
// Else the element can only be present in right
// subarray
int k =binarySearch(arr, mid + 1, r, x);
//modified part
if(k==-1)
{
return binarySearch(arr, l, mid - 1, x);
}
return k;
}
  
// We reach here when element is not present in array
return -1;
}
  
public static int FindIndex(int[] arr, int x)
{
if(arr.length==0)return -1;//if array is empty
return binarySearch(arr,0,arr.length-1,x);
  
}
   public static void main(String[] args) {
   int a[] = {3, 17, 28, 935, 1011, -10, 0, 2} ;//declaring array
   int r = FindIndex(a,935);
       System.out.println("index of 935:"+r);
       r = FindIndex(a,-10);
       System.out.println("index of -10:"+r);
      
       r = FindIndex(a,0);
       System.out.println("index of 0:"+r);
      
       r = FindIndex(a,1);
       System.out.println("index of 1:"+r);
      
       r = FindIndex(a,3);
       System.out.println("index of 3:"+r);
      
       r = FindIndex(a,2);
       System.out.println("index of 2:"+r);
      
       r = FindIndex(a,17);
       System.out.println("index of 17:"+r);

How many types of errors can occur during the execution of a program? Discuss the circumstance when these types of errors can occur. Support your argument with examples.

A professor claimed that wire-based secure communication can be made secure using a continuum, grounded shield around the hot wire carrying the signal. He claimed that, if Eve drills a hole into the shield to probe the hot wire, Alice and Bob could detect the change of the shield resistance and uncover the eavesdropping. Consider tamper resistance. Is such secure communication unconditionally secure?

For an assignment you wrote the method sortByLargestDepth in the class QuakeSortInPlace to sort earthquakes by their depth from largest depth to smallest depth using the selection sort algorithm. Modify this method to do exactly 50 passes and then modify testSort to run this method on the file earthQuakeDataDec6sample2.atom. The file may not be completely sorted as there are more than 50 quakes in the file. After running your program of 50 Selection sort passes on this file, what is the depth of the last earthquake in the ArrayList?

Write a program to declare an array of double of size 25, ask the user to input all array elements from the keyboard, then write a function named out_of_order that will test this array for the condition a[0] >= a[1] >= a[2] >= ... > a[24]

The function returns a -1 if the elements are not out of order, otherwise it returns the index of the first element that is out of order. Explain what you do to avoid out of bounds array access.

Hello, I am using BASH. I need to write a conditional statement using grep. I want the computer to echo true if it detects any numerical character in the first line of StrepList.txt. However, the computer tells me that "grep: [0-9]: No such file or directory"

if (head -n 1 StrepList.txt | grep -o [0-9] -eq TRUE);then

echo "Contains numbers"

else

echo "No numbers"
