Design a data structure that can efficiently manage data packets in a network router. Each data packet consists of the following attributes: Implement the Router class: Router(int memoryLimit): Initializes the Router object with a fixed memory limit. bool addPacket(int source, int destination, int timestamp): Adds a packet with the given attributes to the router. int[] forwardPacket(): Forwards the next packet in FIFO (First In First Out) order. int getCount(int destination, int startTime, int endTime): Note that queries for addPacket will be made in increasing order of timestamp.
