Question 1
Assume Str is a String.
Create your own string (Str), where "length" of the string should be 18.
(The string should be in the form of Str = "ui683ji095ytrd79687df675")
Write a program to print the substring of numbers (n). After printing the substring (n), "sort" them in descending order (d). Then subtract (d-s).
Example:
If Str = qwe598jhk90
substring (n)= 59890
descending order (d)=99850
subtract (d-n)=99850-59890=39960
("Note: You have to create your own method to sort the substring.
(Marks: 10)
Question 2
Encrypted Message = Decrypted Message = Python
(Use "Unicode Table" from "https://cdn.img.onl/thomasorlita.cz/projects/unicode-table.jpg")or given below.
Write a program to showcase the "formula" used for encryption and decryption.
("Note 2: The program should have continuos flow (i.e., Calculate Average-Encrypt-Decrypt)"")
(Marks: 10)

Ask the user to input the "name of file".
Ask the user to input some content into the file and "print the input after writing in the file". (Content should only have Upper Case letters)
Finally, replace the content in the file with "unused alphabets (A-Z)" and write into the file.
Example: If content in the file is "HELLO".
Replace it with "ABCDFGIJKMNPQRSTUVWXYZ"
(Marks: 10)
