Answer to Question #196791 in Algorithms for Adal

Question

1. Allow the user to input integers representing test scores until they enter -1. Store the values as an ArrayList of Integer values. Do not store the -1. Test score values may range between 0 and 100, inclusive. Your program should ignore any value that is outside of the range, and not add it to the ArrayList.
2. Output the list of values entered.
3. Sort the values, lowest to highest and output the sorted list.
4. Find and output the following:
5. average score
6. median score (For an ArrayList with an even number of cells, your program should output the average of the middle two elements. For an ArrayList with an odd number of cells, your program should output the element in the middle.)
7. range of scores (Find the minimum and maximum values in the list.  The range is calculated as: maximum value minus minimum value.)
8. Remove the minimum and maximum values. Output the resulting list.
9. Find and output the following (again):
10. average score
11. median score
12. range of scores

Answer 1

L = []
while True:
    x = int(input('Enter a score (-1 to exit): '))
