   • Variable s1 with the value "foo"
   • Variable s2 with the value "foo"
   • Variable s3 with the value "bar"
   Print all variables and their values to the terminal.

5. Write a test expression that returns a value indicating true or false when testing whether s1 is equal to s2. Echo the results of this test to the terminal.
6. Write a test expression that returns a value indicating true or false when testing whether s1 is not equal to s3. Echo the results of this test to the terminal.
7. Write a test expression that returns a value indicating true or false when testing whether s1 has a length greater than 0. Echo the results of this test to the terminal.
8. Do the following
