You have been provided a starter file that contains Professor Oak$$s student grades as a list of lists. Each

sublist has exactly $6$ items, representing the grades for $($in order$)$ four assignments, a midterm exam, and

a final exam. All grades are out of $100.$ Just copy$/$paste this list to the top of your program. But keep in

mind that your code should work even if we use a different starting list $($though with the same format$)$ to

test your program.

From here, you will write three separate functions to perform three tasks, as described below.

Cleaning the Data

Write a function called clean$\_$grades$()$ that takes the list of lists of grades as a parameter. For all of the

student grades, this function should perform two tasks:

$$ Increase the midterm exam grade for ALL students by $2.$ Recall that the midterm grade is the $5$th item

in each sublist.

$$ For any grade greater than $100,$ set the grade to be just $100($make sure to check for this AFTER

increasing the grade for the midterm exam!$)$

These changes should be done by modifying the input list itself. No new lists should be created and this

function has no return value.
