My regex ensures that invalid examples like \"greg-house@medi_care\" are excluded by forbidding underscores, disallowing trailing dots, and requiring valid domain suffixes.\n\n2. Phone numbers are correctly matched using patterns: \"(+1)-555-678-9012\" supports an optional parenthesized country code followed by dashes, and \"(321).867.5309\" ensures parentheses enclose area codes while dots separate groups. Invalid formats like \"(321)867-5309\" are excluded since they lack a separating punctuation mark.\n\n3. Special alphanumeric IDs like \"X-007-2021-KJ\" require matching a mix of uppercase letters, digits, and hyphens in a specific format.
