Write a method that converts milliseconds to hours, minutes, and seconds using the following header:
public static String convertMillis(long millis)
The method returns a string as hours:minutes:seconds. For example, convertMillis(5500) returns a string 0:0:5,
convertMillis(100000) returns a string 0:1:40, and convertMillis(555550000) returns a string 154:19:10.
