Write a program that reads a file named "gradebook.txt$"$ containing information about a student's grade. The information include the first name and three exam scores.

File Format

The first line contains the number of exams.

The second line contains the name, and the exam scores.

Sample input file

$3,$

Lisa $100,95,80$

You will need to create a new file in onlinegdb and name it "gradebook.txt$".$ There's a file icon on the top left of the code editor. Click on this icon to create a new file. If you do not see this icon, it's because a red ribbon with the message that you haven't confirmed your email is blocking it$.$ Click the $x$ on the red ribbon to the far right.

The output of the program is a table consisting of a name column, average, and grade column. The grade column is optional.

Sample run

$\backslash$table$[[$Nane$,$Avg Grade$],[$Lisa$,91\mathrm{.}67],[$A$,]]$

Here's the logic to solving the problem:

Read the number of exams

Read the name

Read the three exams using a loop and compute the total

Compute the average

Compute the letter grade.

Print the name, average, and letter grade.
