Gets hash value for a string 2. Has correct value for '__ac_HASH_UPPER' 3. Initializes succesfully. 4. Put a key value pair. 5. Gets the value from key. 6. Delete the key-value pair. 7. Updates the value after deleting it. 8. Update Value of before deleting. 9. Contains the right number of elements.
