It $2$: structure programming $($Coding $1)$

$11.$ If a student takes N number of exams $($say five or more$),$ he$/$she would like to calculate the average of the best $x$ exams.

Write a full program that asks for the number of exams $(N),$ then store the required exam grades in a list. The program will then calculate and display the average of the best $(x)$ exams of his$/$her choice, where X must be more than two.

The program must use a function to compute the average of the best $x$ exams in the list. If done using AI I will downvote. Do it as simple as possible.
