Write a program that computes and prints the average of the numbers in a text file. You should make use of two higher-order functions to simplify the design.  Ask the user for the name of the .txt file that contains the list of numbers. Include your code as usual in a .txt AND .py file. Create and use a .txt file to test your code using the numbers 78, 54, 22, 90, 15, 7.
