Your program should follow the following rules:

Prompt the user to enter name, id and score and validates the information.

The student name should be entered as LastName, FirstName (separated by comma). Please note the whole name should be saved in one string.

The student ID must have 7 digits.

The students SCORE must greater or equal to 0 and less or equal to 100.

If the user enters invalid information for each question, your program should repeat the current question.

If the user enters correct information, your program should display the letter grade based on the score. When the letter grade is displayed, the output should be FirstName LastName got SCORE. Based on the grading system, FirstName (ID) will probably get X.
