Question

When a resource is shared among multiple consumers. Examples include CPU scheduling, Disk Scheduling. In the same way as Operating system executes the programs it performs multitasking, multiprocessing, parallel processing, and so on. You are required to build the data structure to handle the multiple processes coming for the execution. As there are many algorithms to execute the process. You need to build the First Come First Service (FCFS).

To solve this problem, implement a data structure that handle the execution of process using FCFS. Create a process class which contain process name and burst time. The following methods are required to be implemented in the structure to organize it.

insertBack(Process): This method will add the process at the last location of processes list.
remove (): This method will delete the process from the first location of processes
getSize(): This method will return the total number of processes that the OS is handling currently.
clear (): This method will erase the process
isEmpty(): This method will checks for the processes in the list. If there is no process in the list than return true otherwise
contains(Process): This method will checks presence of the respective processes in the list. If there is respective process in the list than return true otherwise
