//Problem 12. Call history test
//Write a class GSMCallHistoryTest to test the call history functionality of the GSM class.
//Create an instance of the GSM class.
//Add few calls.
//Display the information about the calls.
//Assuming that the price per minute is 0.37 calculate and print the total price of the calls in the history.
//Remove the longest call from the history and calculate the total price again.
//Finally clear the call history and print it.
