# Consider the function Normalize that takes as input a list of positive numbers
# numbers and returns a list of numbers that are a fraction of the maximum
# element in the list. Try to answer the questions without running the code.
# Check your answers, then run the code for the ones you get wrong. You'll
# learn the most this way, by figuring things out, instead of just running the
# code and reading off the answers.
