"""This code is for monitoring CPU usage. It performs 3 minutes of polling and 3 minutes of monitoring. 
During the 3 minutes of polling, it acquires CPU usage every second and adds it to a list. 
During the 3 minutes of monitoring, it acquires CPU usage every second and adds it to a list.
Finally, it calculates and displays the average value and median value.
