You will write a program to help me determine the final letter grade and

calculate the average score. The steps and requirements are described

below:

$1.$ First, create a dictionary of $10$ students with student name as key and score as

value.

$$ For simplicity, name students as student $1,$ student $2,$ etc. Scores are random integers from $0-$

$100.$

$$ Hint: you know how to use a loop to count from $1$ to $10.$ Use string concatenation, you add

$$student $$ with the control variable i$.$ This will give you student names.

$2.$ Use a FOREACH loop to output each student in terms of the name and score.

$3.$ Calculate and output the average score of the class.

$4.$ Determine and output the letter grade based on the following scheme:

$$ A if score $>=90$

$$ B if $90>$ score $>=80$

$$ C if $80>$ score $>=70$

$$ D otherwise

$$ Overall, you program needs to output the name, score, and letter grade

of each student, and the average score of the class.
