# 5.2 Write a program that repeatedly prompts a user for integer numbers until the user enters 'done'.
# Once 'done' is entered, print out the largest and smallest of the numbers.
# If the user enters anything other than a valid number catch it with a try/except and put out an appropriate message
# and ignore the number.
# Enter 7, 2, bob, 10, and 4 and match the output below: Invalid input, Maximum is 10, Minimum is 2
