Either a message queue management system. A message is characterized by an ID (integer), a priority (integer), and the message itself (string). Write and implement a message scheduler based on a multi-list structure. The multilist structure will contain an ordered list of priority categories implemented statically (with table), and each category will have a circular queue, implemented dynamically (with pointers), to retain messages in that category. Implement the following features: Add priority category (a new category will be added, keeping the list in order) Add message (a message will be added in the queue corresponding to its priority) Message service (the oldest message will be removed from the highest priority category whose queues are not empty) n C programing.
