Create a dictionary containing employee name and id (name:id). Display
Employee names, sorted in alphabetical order
Employee name and id, sorted alphabetically by name
Inverse the dictionary (id : name)

Consider two lists
NAMES = [’Alice’, ’Bob’, ’Cathy’, ’Dan’, ’Ed’, ’Frank’, ’Gary’, ’Helen’, ’Irene’, ’Jack’, ’Kelly’, ’Larry’]
AGES = [20, 21, 18, 18, 19, 20, 20, 19, 19, 19, 22, 19]
These lists match up, so Alice’s age is 20, Bob’s age is 21, and so on. Write a program that
Combines these lists into a dictionary.
Reads a name and returns the age.
Reads an age and returns the names of all the people who are that age.
