Objective of this homework assignment is to practice functions, lists and files.

Problem Description: program generates a list 'Marks' with $30$ data elements which is filled with the random numbers between $40$ and $99.$ Then each of these grades categorized as follows in the list Grades:

$\backslash$table$[[$Marks$,$Grade$],[$Above and equal to $85,$A$],[$Above and equal to $75,$B$],[$Above and equal to $60,$C$],[$Above and equal to $50,$D$],[$Otherwise$,$F$]]$

Display the marks and grade in the tabular format with three columns in a file called 'output.txt$\text{'}.$

Your program should consist of main$()$ and all other functions are called by main$().$

ReadMarks$()$: Generates the list Marks filled with numbers between $40$ and $99$ and returns the list to the main$()$

determineGrades$(...)$: it receives the Marks list and generate a new list called Grades as per above table.

PrintResults$(.....)$: receives the marks and grades list.

Prints the marks and grades in the tabular format and then prints the lowest marks for each grade A$,$ B$,$ C$,$ D$.$

Sample Output:

$\backslash$table$[[,,,,,,],[$hw$4.$py $,$Output.txt $,$A$],[1,82,$B$,63,$C$,98],[2,69,$C$,88,$A$,98,$A$],[3,80,$B$,54,$D$,88,$A$],[4,93,$A$,81,$B$,44,F$
