[LeetCode] 3606. Coupon Code Validator

😎풀이

1. code 확인
   1-1. 빈 값 안됨
   1-2. 영문 대/소문자 및 정수와 _외 안됨
2. businessLine 확인
   2-1. electronics, grocery, pharmacy, restaurant 외 안됨
3. isActive는 true 여야 함
4. 해당되는 활성화 티켓을 이전 언급한 businessLine 순서로 오름차 순 정렬 즉 electonics ~ restaurant
5. 쿠폰 code를 사전 순 오름차 순 정렬
6. 정렬된 활성화 티켓 목록 반환
