Variable groceryArchive is declared as a HashSet. Then, integer numGroceries is read from input representing the number of strings to be read next. For each string read into variable grocery:

Add grocery to groceryArchive.

If grocery is successfully added, output "Grocery entered: $",$ followed by grocery.

Otherwise, output "Duplicate found: $",$ followed by grocery, and assign duplicateEncountered with true.

End each output with a newline.

Ex: If the input is:

$4$

mushrooms mushrooms oranges bananas

then the output is:

Grocery entered: mushrooms

Duplicate found: mushrooms
