- A company wants to transmit data over the telephone, but it’s concerned that its phones may be tapped. All of its data is transmitted as four-digit integers. It has asked you to write a script that will encrypt its data so that the data may be transmitted more securely. Your script should read a four-digit integer entered by the user in a prompt dialog and encrypt it as follows: Replace each digit by (the sum of that digit plus 7) modulus 10. Then swap the first digit with the third, and swap the second digit with the fourth. Then output HTML5 text that displays the encrypted integer.RStudio How to filter these data so that 1 and 2 are the headers in RStudio?

What is the encrypted animal name (enter a string of letters with no spaces)? Decrypt An animal name was encrypted with the scheme described in the previous question (it was encoded with the key 3). The encrypted animal name is pduprw .What is the animal name?HTTP is the protocol that governs communications between web servers and web clients (i.e. browsers). Part of the protocol includes a status code returned by the server to tell the browser the status of its most recent page request. Some of the codes and their meanings are listed below: • 200, OK (fulfilled) • 403, forbidden • 404, not found • 500, server error Given an int variable status, write a switch statement that prints out, on a line by itself, the appropriate label from the above list based on status.A palindrome is a number or a text phrase that reads the same backward and forward. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a script that reads in a five-digit integer and determines whether it’s a palindrome. If the num- ber is not five digits long, display an alert dialog indicating the problem to the user. Allow the user to enter a new value after dismissing the alert dialog.

You have managed to intercept a message that reads as follows: :mmZ\dxZmx]Zpgy The message is obviously encrypted using a secret code. You have just learned that the used encryption method is based upon the ASCII code (available online). Individual characters in a string are encoded using this system. For example, the letter "A" is encoded using the number 65 and "B" is encoded using the number 66. The secret code takes each letter of the message and encrypts it as follows: if (OriginalChar + Key > 126) then EncryptedChar = 32 + ((OriginalChar + Key) – 127) else EncryptedChar = (OriginalChar + Key) For example, if the Key = 10 is used then the message "Hey" would be encrypted as: Character ASCII code H 72 e 101 y 121 Encrypted H = (72 + 10) = 82 = R in ASCII Encrypted e = (101 + 10) = 111 = o in ASCII Encrypted y = 32 + ((121 + 10) – 127) = 36 = $ in ASCII Consequently, "Hey" would be transmitted as "Ro$."
