User entries: I've crafted a pattern to match the exact 3 valid [USER:#xxx:xx-xx@xxx] formats while avoiding the invalid entries (missing # or misspelled).\n\n4. Transaction codes: For the 2 valid TXN entries, I'm using alternation to match the exact values with their specific dates and amounts.\n\n5.
