$4.[6$ points.$]$ Structured Output II $-$ Printing Tables. You should turn in one m$-$file for this problem.

Recall that in the lecture, we saw that textread provides a powerful way to read data from file. We saw that we can read all the file grades.txt using

$[$id test$1$ test$2]=$ textread$($grades$.$txt$,\%$s $\%$f $\%$f$)$;

which stores the student id$,$ test$1$ scores, test$2$ scores into the vectors id$,$ test$1,$ test$2.$ Write a script gradeReport$2.$m that uses textread to read the data as above and then write a table showing the following information for each student: student id$,$ score for test$1,$ score for test$2,$ average score, and a letter grade $($corresponding to the average score$)$ to a file called output.txt $.$ Note that you will be using the function score$1$ from the previous class to get letter grades.

The output should look like the following, using the indicated format for the real numbers:
