Explanation of Solution

“Image” and “ImageView” classes:

Displaying an image in JavaFx involves two steps, they are:

  • Fetching image from the input stream or location.
  • Displaying an image.

To perform these operations, JavaFx uses two classes, they are “Image” and “ImageView” classes.

  • “Image” class is used to load graphical images, which can be displayed with the help of “ImageView” class.
  • The package used for the image class is “javafx.scene.image.Image” which help to load the image from the URL or filename.
  • It is possible to set one image to many “ImageView” because, one image can be displayed in multiple views. Whereas, it is not possible to display one “ImageView” multiple times because an “ImageView” node cannot be shared...

We are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure.  Alice's public key (n,public_key) is (247,7). A code breaker manages to factories  247 = 13 x 19  Determine Alice's secret key. To solve the problem, you need not use the extended Euclid algorithm, but you may assume that her private key is one of the following numbers 31,35,55,59,77,89.
Consider the following Turing Machine (TM). Does the TM halt if it begins on the empty tape? If it halts, after how many steps? Does the TM halt if it begins on a tape that contains a single letter A followed by blanks? Justify your answer.
