Logger Rate Limiter

We can use a hash table to record the latest logged time of a log to decide whether to log.

Code in Python:

class Logger(object):

    def __init__(self):
        """
        Initialize your data structure here.
        """
        self.log = {}

    def shouldPrintMessage(self, timestamp, message):
        """
        Returns true if the message should be printed in the given timestamp, otherwise returns false.
        If this method returns false, the message will not be printed.
        The timestamp is in seconds granularity.
        :type timestamp: int
        :type message: str
        :rtype: bool
        """
        if message not in self.log:
            self.log[message] = timestamp
            return True

        if self.log[message] > timestamp-10: return False

        self.log[message] = timestamp
        return True


# Your Logger object will be instantiated and called as such:
# obj = Logger()
# param_1 = obj.shouldPrintMessage(timestamp,message)
