알고리즘 풀이

처음에는 Arrays.sort([array], Collections.ReverseOrder()) 이거로 Reverse하고 Delete하고 Reverse하고.. 이런 식으로 하는 건줄 알았는데 element의 양이 많고 삭제가 빈번하다는 점에서 LinkedList를 사용해야하는 것을 깨달았음 (바로 LinkedList를 써야겠군 이정도도 안되는 수준임 지금) 각 TestCase마다 결과 String을 출력할 수 있도록 부분적인 기능을 하는 함수들을 만듬 1. String을 Parsing해서 숫자를 추출해 LinkedList를 return하는 함수 2. 1번에서 return받은 LinkedList를 명령어(ex)"RDD", "DD", "RRD")에 맞게 LinkedList 양끝단을 잘라내는 함수 ※ 2번 함..
