Products with Proper Serials

Return products whose serial_number matches exactly the pattern SN- + exactly 4 digits (e.g. SN-1234). Return product_id and product_name.

Expected output sample

This is what a correct answer looks like — its row count is its own, it doesn't have to match the schema tables. Your answer must use the same column names as this sample — alias them with AS if needed.

product_id	product_name
1	Widget
3	Thing
7	Nut
