같은 message가 10초 안에 다시 Print 되지 않도록 확인하는 함수를 만들면 된다. 파이썬의 해시맵을 사용해 해당 message의 timestamp를 확인하고 갱신해 True/False를 반환한다. class Logger: def __init__(self): self.d = defaultdict(int) def shouldPrintMessage(self, timestamp: int, message: str) -> bool: if message not in self.d: self.d[message] = timestamp return True else: if timestamp - self.d[message] < 10: return False else: self.d[message] = timestam..

난이도는 Easy로 아래와 같다. Design a logger system that receives a stream of messages along with their timestamps. Each unique message should only be printed at most every 10 seconds (i.e. a message printed at timestamp t will prevent other identical messages from being printed until timestamp t + 10). All messages will come in chronological order. Several messages may arrive at the same timestamp. Imple..
