Write a program that computes the difference between two time
readings. The times are read into the program as integers of at most 6
digits (without leading zeros):`hhmmss`, where `hh`
stands for hour, `mm` minutes and `ss` seconds. The
difference should be displayed in the same format. The difference can
be both positive and negative. You can assume, for now, that the
inputs are correct (that is, you are not going to have more than 59
seconds or more than 59 minutes).

Ex:

Enter first 6-digit time: 23245 Enter second 6-digit time: 32815 Time difference: 5530 Enter first 6-digit time: 123245 Enter second 6-digit time: 112955 Time difference: -10250

- The above example is for
**2 separate runs**. - The best way to compute the difference is to:
- Isolate the diferent parts of each time: hours, minutes and
seconds (use the mod operator
`%`... hint, hint, hint). - Compute the time in terms of seconds (1 hour = 3600 seconds, 1 minute = 60 seconds).
- Compute the difference in seconds.
- Convert the above number into hours, minutes and seconds
(again the mod operator
`%`, but with a different base ... hint, hint, hint). *Build*the new 6-digit integer.

- Isolate the diferent parts of each time: hours, minutes and
seconds (use the mod operator
