Leetcode:logger Rate Limiter

Design a logger system this receive stream of messages along with its timestamps, each message should be printedifand onlyifIt isn't printed in the last 10seconds. Given a message and a timestamp (in seconds granularity),return true ifThe message should is printed in the given timestamp, otherwise returnsfalse. It is possible this several messages arrive roughly at the same time. Example:logger Logger=NewLogger ();//Logging string "foo" at timestamp 1Logger.shouldprintmessage (1, "foo"); Returnstrue; //Logging string "Bar" at timestamp 2Logger.shouldprintmessage (2, "bar"); Returnstrue;//Logging string "foo" at timestamp 3Logger.shouldprintmessage (3, "foo"); Returnsfalse;//Logging string "Bar" at timestamp 8Logger.shouldprintmessage (8, "bar"); Returnsfalse;//Logging string "foo" at timestampLogger.shouldprintmessage (Ten, "Foo"); Returnsfalse;//Logging string "foo" at timestampLogger.shouldprintmessage (One, "foo"); Returnstrue;
