Consider the following code snippet. What should be placed in the blank to cause a message to be displayed when the user enters the same letter twice in a row? letter = input ("Enter the next letter in the alphabet: ") while letter != "": previous = letter letter = input ("Enter the next letter") if print ("Duplicate input") a. letter == letter O b. alphabet[0] == letter =3%3D O c. alphabet[0] == previous 3D= Od. letter == previous

write a program that inserts parentheses, a space, and a dash into a string of 10 user-entered numbers to format it as a phone number. for example 5555555555 becomes (555) 555-5555. If the user does not enter exactly 10 digits, display an error message. continue to accept user input until the user enters 999 using string builder.
Write an application that determines whether a phrase entered by the user is a palindrome. A palindrome is a phrase that reads the same backward and forward without regarding capitalization, spaces or punctuation. And it will allow the user to enter as many phrases as he likes after each iteration.
Write a program that asks the user to enter 10 numbers, that range from 10-100. Make sure that you do not accept any numbers less than 10, if a user enters a number that is less than 10 then ask him again. Once the user enters all 10 numbers, sort the numbers entered in ascending order and print them out. CSharp
Write a program that inserts parentheses, a space, and a dash into a string of 10 user-entered numbers to format it as a phone number. For example, 5153458912 becomes (515) 345-8912. If the user does not enter exactly 10 digits, display an error message. Continue to accept user input until the user enters 999 (see screen shots next slide).
Write a program that • Requests a temperature from the user. • Also asks if the temperature is in Fahrenheit (F) or Celsius (C). • Converts the entered temperature to the other scale. • Prints out the result as illustrated below. The conversion formulas are c=등(F-32) F =C+ 32 and
Create a program that reads integers from the user until the enter key is pressed. Onceall of the integers have been read your program should display all of the negativenumbers, followed by all of the zeros, followed by all of the positive numbers. Withineach group the numbers should be displayed in the same order that they were enteredby the user. For example, if the user enters the values 3, -4, 1, 0, -1, 0, and -2 thenyour program should output the values -4, -1, -2, 0, 0, 3, and 1. Your programshould display each value on its own line.

One interesting application of computers is drawing graphs and bar charts (sometimes called histograms). Write a script that reads five numbers between 1 and 30. For each number read, output HTML5 text that displays a line containing the same number of adjacent asterisks. For ex- ample, if your program reads the number 7, it should output HTML5 text that displays *******.
Write a program that prompts the user to enter a sequence of numbers until a -999 is entered. It will print the numbers the user entered, five number in a row,with a before the first number and after the last number in each row. For example, Enter a number (-999 to stop): 23Enter a number (-999 to stop): 15Enter a number (-999 to stop): 1Enter a number (-999 to stop): 7Enter a number (-999 to stop): 9Enter a number (-999 to stop): 21Enter a number (-999 to stop): 17Enter a number (-999 to stop): 33Enter a number (-999 to stop): -999[23 15.17 9] [21 17 33]
Homework: Homework01. Write a Java program that prompts the user to enter the seconds as a String (e.g., "1500500500"), converts the received value to long, and displays the number of years and days for the received seconds. For simplicity, assume a year has 365 days. Here is a sample run: Enter the number of seconds: 1500500500 '1500500500' seconds is approximately '4' years and '2766' days
10-6. Addition: One common problem when prompting for numerical input occurs when people provide text instead of numbers. When you try to convert the input to an int, you’ll get a ValueError. Write a program that prompts for two numbers. Add them together and print the result. Catch the ValueError if either input value is not a number, and print a friendly error message. Test your program by entering two numbers and then by entering some text instead of a number.
