🍑 알고리즘 설계
풀이 과정에서 본인이 생각한 내용을 작성해 주세요.
시간을 분단위로 바꾸면서 우선순위 큐를 이용해서 정렬했습니다. 그런 다음 방들의 퇴실시간과 현재 입실시간을 비교해서 큐에 넣고 뺴는 방식을 활용했습니다.
while(!t_arr.isEmpty()){
int[] curr = t_arr.poll();
if(room.isEmpty()){
room.offer(curr[1]);
count++;
}else{
int prev = room.peek();
if(prev <= curr[0]){
room.remove(prev);
room.offer(curr[1]);
}else{
room.offer(curr[1]);
count++;
}
}
