To implement LRU, each page uses a referenced bit. If we wanted to implementa least frequently used (LFU) page removal algorithm, where the least-usedpage would be removed from memory. what would we need to add to thetables? What software modifications would have to be made in order tosupport this new algorithm?

Test failed when processing: two networks (CODE: FetchRoute Table2) Test failed when processing: fully-connected mesh (CODE: FetchRoute Table19) Test failed when processing: an arbitray networks (CODE: FetchRoute Table8) Test crashed when attempting to mark an arbitrary network with unreachable destinations Test failed when processing: the weights on routes (CODE: FetchRoute Table8) Program does not seem to have sufficient implementation to test memory usage dijkstra() correctly returns NULL if an invalid source network is passed
