Write a Java program that allows a teacher to enter student scores for an assignment. When the program starts, ask the user how many grades they would like to enter.

Note: You do not need to perform input validation for this problem.

After the grades have been entered, print out the average score for the assignment. Then, in a file named "scores.txt", append the name of the assignment, a colon, and the average. For example, if the user entered "Homework #1" for the assignment name and the average score was calculated as 93:
