The Summer Olympics

The Summer Olympics take place every four years in different location around the world. Using the data from the table below, create a hash summer_olympics, using the city as the hash's key and the year as the hash's value. Use :symbols instead of string for the keys.

Place	Year
Sydney	2000
Athens	2004
Beijing	2008
London	2012

Add A Key Value Pair

The 1996 summer olympics took place in Atlanta. Add this information to the hash.

Iterate Through the Hash

Use the .each method to iterate through the summer_olympics hash and for each key-value pairputs a string that reads "The _____ summer olympics took place in ______."

Iterate Through the Keys

Use the each_key method to return an array of the cities where each city name has been upcased. Save this to a new variable called upcased_cities and puts this to the screen.
