목록은 비연속적인 메모리 할당을 허용하는 시퀀스 컨테이너입니다. 목록은 벡터에 비해 탐색이 느리지만 위치를 찾으면 삽입 및 삭제가 빠릅니다.
기능 및 설명:
From main(), we have called following functions: fl.resize() = Returns the resize of list. fl.push_front() = It is used to push elements into a list from the front. fl.remove() = Deletes elements from list. fl.unique() = Deletes duplicate elements from list. fl.reverse() = Reverses the list. fl.front() = Returns the front element of list.
