| // EXERCISE: Add Split Seconds
 | |
| //
 | |
| //  Your goal is adding the split second to the clock. A split second is
 | |
| //  1/10th of a second.
 | |
| //
 | |
| //  1. Find the current split second
 | |
| //  2. Add dot character to the clock (as in the expected output)
 | |
| //  3. Add the split second digit to the clock
 | |
| //  4. Blink the dot every two seconds (just like the separators)
 | |
| //  5. Update the clock every 1/10th of a second, instead of every second.
 | |
| //     (Update the clock every 100 millliseconds)
 | |
| //
 | |
| // HINTS
 | |
| //   + You can find the split second using Nanosecond method of the Time type.
 | |
| //     https://golang.org/pkg/time/#Time.Nanosecond
 | |
| //
 | |
| //   + A split second is the first digit of the Nanosecond.
 | |
| //
 | |
| //   + Remember: time.Second is an integer constant, so it can be divided
 | |
| //               with a number.
 | |
| //
 | |
| //     https://golang.org/pkg/time/#Time.Second
 | |
| //
 | |
| // EXPECTED OUTPUT
 | |
| //     Note that, clock is updated every split second instead of a second.
 | |
| //
 | |
| //     Separators are displayed (second is an odd number):
