DIY: Logger Rate Limiter

Problem statement

Design a logger system that receives a stream of messages and their timestamps. Each message should be printed if and only if it is not printed in the last 5 seconds.

Input

The input will be a stream of messages and their timestamps in the following format:

func(timestamp, message)

Output

The output will be a Boolean variable in the form of either true or false.

Coding exercise

Implement the shouldPrintMessage(timestamp, message) function, where timestamp is the time of arrival of the message and message is the text which you need to store. The function returns true if the message will be printed in the given timestamp. Otherwise, it returns false. It is possible that several messages arrive at roughly the same time.
