Write a Java program that prompts the user to enter:

- a two character string containing only lowercase characters in the range az

- a three character string consisting of a lowercase letter in the range az, followed by two digits (each in the range of 0 to 9, inclusive)

The program must use validation, and prompt the user to retry if either of the entries is invalid. When both of the inputs are valid, the program should output to a file in CSV format as follows:

- write each of the user inputs on line 1 of the file

- write LP as the last value on line 1 of the file

- write, on line 2 of the file, the numeric equivalent of each individual letter from the first line, separated by commas.

- Assume a=A=1, b=B=2, ..., z=Z=26.

- write, on line 3 of the file, the sum of the values of line 2

The file name should be of the format YYYYMMDDIN.txt where:

- YYYYMMDD is the date the program is run (in year month day format)

- IN are the initials of your name

- .txt is the filename extension

- Example filename: 20220112LP.txt

Example program execution (user entry is shown in green italics): Please enter a string of two az characters: ac

Please enter a string of three characters (az followed by two digits): k12 E

xample file contents (with comma-separated values):

ac,k12,LP

1,3,11,3,18

The sum of the values in the second row is: 36
