I need help with a step by step guide to solving this problem. this requires the creation of BaseLinkedUrgencyQueue, CustomLinkedUrgencyQueue and LinkedUrgencyQueue as the diagram depicts. They use pre$-$created node and UrgencyQueue so stating exactly what is imported to where would be appreciated. this is run through an emacs, if more information is required simply look up cs$1302$ Urgency$-$queue and its the first GitHub link if the pictures aren't sufficient enough. Again please include exactly what is imported, it should look like import cs$1302.$gen.UrgencyQueue; or import cs$1302.$gen.Node; and so on$.$ the program calls for the use of pre$-$established node and UrgencyQueue so another whole node class shouldn't be required. This is my $3$rd or $4$th time so I$\text{'}$d appreciate if the program operated without problems. Thanks
