By defining a two$-$dimensional $($matrix structure$)$ array of type M x N$,$ where M $=10,$ N $=5,$ the grades of N courses of the class of M people are entered from the keyboard. According to this;

$-$ The arithmetic average of the class from each course,

$-$ Grade point average of each student,

Write a program in Python programming language that calculates the $($row$)$ number and average grade of the students with the highest and lowest grade point averages and displays them on the screen. Explain why you used each command you wrote and what its function is$.$
